What example of scientific thinking does Bohr response best indicate
Answer:
The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure 1). These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells

What neutral element has the electron configuration described by the Aufbau diagram above.
Answer:
Aluminium.
Explanation:
The above electronic configuration can be written in a simplified form as shown below:
1s² 2s²2p⁶ 3s²3p¹
Next, we shall determine the number of electrons in the atom of the element as follow:
Number electron = 2 + 2 + 6 + 2 + 1
Number of electron = 13
Next, we shall determine the number of protons.
Since the element is in its neutral state,
The number of electrons and protons are equal i.e
Proton = Electron
Number of electron = 13
Proton = Electron = 13
Proton = 13
Next, we shall determine the atomic number of the element.
The atomic number of an element is simply the number of protons in the atom of the element i.e
Atomic number = proton number
Proton = 13
Atomic number = 13
Comparing the atomic number of the element with those in the periodic table, the element with the above electronic configuration is aluminium since no two elements have the same atomic number.

yo someone please help meee The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.69 m on each side?
Mass of the cube of silver is 3,449.34 kg
First find the volume of the cube in centimeters because the density is in centimeters:
0.69 * 100 = 69 centimeters
Volume = Side * Side * Side
= 0.69 x 0.69 x 0.69
= 328,509 cm³
The density of a material is calculated by the formula:
= Mass / Volume
As you have the density already and the volume, you can get the mass:
10.5 = Mass / 328,509
Mass = 10.5 * 328,509
= 3,449,344.50 grams
A kilogram is 1,000 grams so the mass in kg is:
= 3,449,344.50 / 1,000
= 3,449.3445 kilograms

How do atoms emit light ?
Answer:
The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted.
Why are some isotopes radioactive and some are not?
Answer: there are atoms that either have too many or too few neutrons or protons in their nuclei. This results in an imbalance between the jedi forces holding them together, which leads to an excess of internal energy. Such atoms are said to be unstable or radioactive.
Explanation:
Why do atoms always contain the same number of electrons and protons?
Answer:
An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.
Answer:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

If a gas has a mass of 468 grams and its density is 17 grams per liter, how much volume does it occupy?
Answer:
The answer is
27.53 LitresExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{Density} [/tex]
From the question
mass = 468 g
Density = 17 g/L
Substitute the values into the above formula and solve
We have
[tex]volume = \frac{468}{17} \\ = 27.529411[/tex]
We have the final answer as
27.53 LHope this helps you
