Question

1. name the three particles of the atom and their respective charges are: a. ___________ _________ b. _________ _________ c. _________ _________ 2. the number of protons in one atom of an element determines the atom’s _________, and the number of electrons determines ___________ of an element.

Explanation:

1. Atoms are composed of three main particles. Protons have a positive charge and are in the nucleus. Neutrons have no charge and are also in the nucleus. Electrons have a negative charge and orbit the nucleus.
2. The number of protons in an atom determines its atomic number. In a neutral atom, the number of electrons equals the number of protons, and the electrons are involved in chemical - bonding, thus determining the chemical properties of an element.

Answer:

1.
a. Proton, Positive charge
b. Neutron, No charge
c. Electron, Negative charge

1. Atomic number, Chemical properties
