What is the role of
electrons within an
atom?
A.
Electrons are in the nucleus and have a
negative charge
B. Electrons are in the nucleus and have a
positive charge
C. Electrons are outside the nucleus and
have a negative charge
D. Electrons are outside the nucleus and
have a positive charge

Answers

The answer would be “C” because electrons are found in the outer layer of an atom, and they are also negatively charged.

Option C - Electrons are outside the nucleus and and have a negative charge is the correct alternative.

We have electrons.

We have to determine their role inside the atom.

What are Electrons ?

An electron is one of the subatomic particles within an atom. It is negatively charged particle whose magnitude is 1.6 x 10⁻¹⁹ C.

According to the question -

The role of electrons inside the atom is as follows -

Electrons revolve around the nucleus.They carry a negative - charge of  -1.6 x 10⁻¹⁹ C.

Hence, Option C is the correct alternative.

There are  20 nitrogen atoms in the chemical formula mentioned.

What is chemical formula?

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.They are used to describe the chemical reactions.

There are four types of chemical formula:

1)empirical formula

Why are electron filling orders not the same between the first and the last two elements of group 6B?​

Answers

Answer:

This primarily has to do with the balance of energy between the orbitals. The aufbau principle states that the order of energy regarding electrons in the orbitals from lowest to highest is so the electron in the atom will minimalize it's energy. Periods on the periodic table are based on the energy level while the groups have the same amount of valence electrons. The outer orbitals are refered to as shells. The elements are particularly arranged depending on their atomic and molecular orbitals. Valence electrons most determine the chemical properties of an element. The atomic number is based on the number of protons.

Answers

Answer:

the last one

Explanation:

ydyeusueueueueudhs

Because hydrogen forms compounds with oxidation numbers of both +1 and -1, many periodic tables include this element in both Group IA (with Li, Na, K, Rb, Cs, and Fr) and Group VIIA (with F, Cl, Br, I, and At).

There are many reasons for including hydrogen among the elements in Group IA. It forms compounds (such as HCl and HNO3) that are analogs of alkali metal compounds (such as NaCl and KNO3). Under conditions of very high pressure, it has the properties of a metal. (It has been argued, for example, that any hydrogen present at the center of the planet Jupiter is likely to be a metallic solid.) Finally, hydrogen combines with a handful of metals, such as scandium, titanium, chromium, nickel, or palladium, to form materials that behave as if they were alloys of two metals.

There are equally valid arguments for placing hydrogen in Group VIIA. It forms compounds (such as NaH and CaH2) that are analogs of halogen compounds (such as NaF and CaCl2). It also combines with other nonmetals to form covalent compounds (such as H2O, CH4, and NH3), the way a nonmetal should. Finally, the element is a gas at room temperature and atmospheric pressure, like other nonmetals (such as O2 and N2).

It is difficult to decide where hydrogen belongs in the periodic table because of the physical properties of the element. The first ionization energy of hydrogen (1312 kJ/mol), for example, is roughly halfway between the elements with the largest (2372 kJ/mol) and smallest (376 kJ/mol) ionization energies. Hydrogen also has an electronegativity (EN = 2.20) halfway between the extremes of the most electronegative (EN = 3.98) and least electronegative (EN = 0.7) elements. On the basis of electronegativity, it is tempting to classify hydrogen as a semimeta

Consider the following intermediate chemical equations.

CO(g)+302(g) → CO2(g)
How will oxygen appear in the final chemical equation?
O O2(g) as a product
O O2(g) as a reactant
O O(g) as a product
O 20(g) as a reactant

Answers

O₂(g) as a reactant

Further explanation

In chemical reactions, there is a reaction between reagents and products

Reaction:

aA + bB ⇒ cC

Substances A and B are called a reactants

Substance C is called a product

In the above reaction:

Reactants: C, O₂ and CO Products: CO and CO₂

CO functions as a product in the first reaction and functions as a reactant in the second reaction  

In the final chemical equation :

CO(g)+30₂(g) → CO₂(g)

O₂ is on the left so it is called the reactant

Answer: B. O₂(g) as a reactant

Spongebob completed his experiment. He wrote a brief summary about the investigation. He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation. Spongebob utilized which step of the scientific method?

Answers

Answer:

In a 7-step scientific method, Spongebob utilized the 6th step when He wrote a brief summary of the investigation, and Spongebob utilized the 7th step when He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation.

Explanation:

Scientific Methods are organized ways employed by scientists to tackle problems by providing solutions to the problem or make hypotheses to which other scientists build on to provide solutions to the problem.

The steps of the scientific method are:

Step 1- Understand the Problem

Step 2-  Make research

Step 3- Hypothesis.

Step 4- Conduct an experiment to test the hypothesis

Step 5- Observations.

Step 6-Results/Conclusion.

Step 7- Communicate your research

When Spongebob wrote a brief summary of the investigation, which means he had already conducted an experiment and had already made necessary observations and data collection, so he was at step 6. At step 6, he had analyzed the data collected.

When Spongebob determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation, then he was at the final step of the scientific method. Step 7 tells whether the hypothesis is true or false.
