40POINTS AND BRAINLIEST Discuss the orders in which electrons are filled in the s and d subshells of the first three elements in group11
Step 1: add electrons to fill the 1s subshell (maximum of 2 electrons), when this is full, go to step 2. Step 2: add electrons to fill the 2s subshell (maximum of 2 electrons), when this is full, go to step 3. Step 3: add electrons to fill the 2p subshell (maximum of 6 electrons), when this is full, go to step 4. Step 4: add electrons to fill the 3s subshell (maximum of 2 electrons), when this is full, go to step 5. Step 5: add electrons to fill the 3p subshell (maximum of 6 electrons), when this is full, go to step 6. Step 6: add electrons to the 4s subshell (maximum of 2 electrons), when this is full, go to step 7. Step 7: add electrons to the 3d subshell (maximum of 10 electrons), when this is full, go to step 8. Step 8: add electrons to the 4p subshell (maximum of 6 electrons), when this is full, go to step 9. etc
So for Cu would be: 1s^22s^22p^63s^23p^63d^9
Ag would be: 1s^22s^22p^63s^23p^63d^104s^24p^64d^105s^1
Au would be: 1s^22s^22p^63s^23p^63d^104s^24p^64d^105s^25p^64f^145d^106s^1
How can you tell if an element is a metal or a nonmetal??
Answer:
Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table.
Explanation:
Answer:
looking at its metallic luster
Explanation:
Elements may be classified as either metals or nonmetals based on their properties. Much of the time, you can tell an element is a metal simply by looking at its metallic luster, but this isn't the only distinction between these two general groups of elements. Most elements are metals.

Gases ___ out and fill their container completely
Answer: Gases have the lowest density of the three, are highly compressible, and completely fill any container in which they are placed. Gases behave this way because their intermolecular forces are relatively weak, so their molecules are constantly moving independently of the other molecules present. Solids, in contrast, are relatively dense, rigid, and incompressible because their intermolecular forces are so strong that the molecules are essentially locked in place.

how many molecules are in CO²
Answer:
53.11× 10²³ molecules
Explanation:
Given data:
Number of molecules of CO₂ = ?
Mass of CO₂ = 388.1 g
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of CO₂ = 12× 1 + 16×2
Molar mass of CO₂ = 44 g/mol
Now we will put the values in formula.
Number of moles = 388.1 g/ 44 g/mol
Number of moles = 8.82 moles
Now we will calculate the number of molecules by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
8.82 mol × 6.022 × 10²³ molecules / 1 mol
53.11× 10²³ molecules
Brainliest plz?
Answer:
Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present.
Explanation:
We know the molar mass of CO2(g) is 44.01⋅g⋅mol−1 . And so Avogadro's number of carbon dioxide molecules have this mass... And we take the product of the quotient... Molecules of carbon dioxide=5.00⋅mol×6.022×1023⋅mol−1≅30×1023⋅carbon dioxide molecules.

200.7 pm = _________________________nm
0.000357 hm = ______________________cm
14.78 mg = __________________________ g
8.280 μg = __________________________pg
Answer:
0.2007 nm
3.57 cm
0.01478 g
8280000 pg
Explanation:
1)200.7 pm
1 picometer is equal to 0.001 nanometer.
1 nm = 1000 pm
200.7 pm× 1 nm / 1000 pm = 0.2007 nm
2)0.000357 hm
1 hectometer is equal to 10,000 centimeter.
1 hc = 10,000 cm
0.000357 hc× 10,000 cm / 1 hc = 3.57 cm
3) 14.78 mg
1 gram is equal to 1000 milligram.
1 g = 1000 mg
14.78 mg × 1 g/1000 mg = 0.01478 g
4)8.280 µg
1 microgram is equal to 10⁶ picogram.
1 µg = 1000000 pg
8.280 µg× 10⁶ pg/ 1µg = 8.280×10⁶ pg or 8280000 pg

An airplane travels east with a velocity of 90 m/s. How long does it take the airplane to cover a distance of 405 meters?
A. 4.5 seconds
B. 60.0 seconds
C. 90.0 seconds
D. 3.0 seconds
Answer:
The answer is option AExplanation:
To find the time taken given the velocity and distance covered we use the formula
[tex]t = \frac{d}{v} \\ [/tex]
From the question we have
[tex]t = \frac{405}{90} \\ [/tex]
We have the final answer as

Why are prefixes used in naming covalent compounds?
A. The prefixes identity the only way the atoms can combine.
B. The same atoms can combine in more than one ratio.
C. The atoms can have different numbers of valence electrons
D. Oxidation states of the atoms are identified with prefixes
Answer:
B
Explanation:
The same atoms can combine in more than one ratio.
The same atoms can combine in more than one ratio. Hence, option B is correct.
What is a covalent bond?A covalent bond shares one or more pairs of electrons between two atoms.
Covalent bonds are the bond between non-metals that are linked together by shared electrons. Covalent compounds are named with different prefixes to identify the number of atoms in the molecule.
Hence, option B is correct.

If a gold bar is 16,000 g mass and 800 cm^3 volume what is the density?
Answer:
The answer is 20 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 16,000 g
volume = 800 cm³
We have
[tex]density = \frac{16000}{800} = \frac{160}{8} \\ [/tex]
We have the final answer as
20 g/cm³Hope this helps you

how do you balence this
Answer:
As the number of atoms in the reactants side is equal to the number of atoms in the product side, the reaction is balanced
Two hydrogen molecules per oxygen molecule are produced because water (H2O) has a ratio of two hydrogen atoms to one oxygen atom. A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O. Water is chemical substance with no smell, taste or color.
You crumple a piece of paper in your hands. Not all of the kinetic energy from your hands is used to crumple the paper. Where does the rest of the energy go?
A. It is transformed into sound energy.
B. It is transformed into light energy.
C. It is transformed into electrical energy. D. It is transformed into magnetic energy.
Answer:
A
Explanation:
When you crumble a piece of paper it make a sound plus i just did on apex
When we crumple a piece of paper in our hands, a part of the energy is transformed into sound energy. Therefore, option (A) is correct.
What is sound energy?Sound transmits through the medium such as liquids, gases, and plasma in the form of longitudinal waves or compression waves. It requires a medium to propagate as it can travel through solids as both longitudinal and transverse waves.
Transverse sound waves exhibit waves of alternating shear stress perpendicular to the direction of propagation while Longitudinal sound waves exhibit alternating pressure deviations leading to compression and rarefaction.
Generally, waves move matter up and down but do not carry along. When we crumple the paper with our hands the kinetic energy of our hands is used to deform the paper but at the same time, we can listen to some sound which indicates that some energy is transformed into sound energy.
