1. The number of protons in an atom equals the elemental identity, or the atomic number.

2. Electrons are negatively charged particles circling the nucleus in the electron cloud surrounding the atom.

3. Matter comprised of only one type of atom is an element.

4. The building block of matter is the atom.

5. Neutral particles within the nucleus are neutrons. They serve to bind the atom together by negating the repulsive force of the protons.

6. The center of the atom is the nucleus.

7. The positively charged particle is the proton.

Answer from: kalo1023

Explanation:

1. Number of protons in an atom → atomic number

An atomic number of an neutral atom is equal to total number of protons present in its nucleus.

2. Negatively charged particle circling nucleus → electron

It is the first subatomic particles discovered by scientist J.J. Thomson.

3. Matter made up of just one type of atom → element

An element is composed of same kind of atom where as in compound different types of atoms are associated with each other

4. Building block of matter → atom

The fundamental unit of a matter.

5. Neutrally charged particle nucleus → neutron

It is a third subatomic particles discovered by scientist named Chadwick

6. Center of the atom made up of protons and neutrons → nucleus

A nucleus of an atom is in center of an atom in which whole mass of an atom is concentrated.It includes protons and neutrons

7. Positively charged particle in the nucleus → proton

Positively charges species or second subatomic particle of an atom which was discovered by scientist named Rutherford.
