Question

B. Define the following terms.
1. Atoms 2. Radicals 3. Electrons​

Answer 1

Answer:

1.)An atom is the smallest unit of ordinary matter that forms a chemical element.

2.) In chemistry, a radical is an atom, molecule, or ion that has an unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive.

3.) Electrons are the subatomic particles that orbit the nucleus of an atom. They are generally negative in charge and are much smaller than the nucleus of the atom

Explanation:

I hope it helps.

Answer 2

Explanation:

The smallest particle of a chemical element that exist is called an atom.

A radical is a molecule that has one unpaired electron on the oxygen atom.

Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus.
