Answer:
Protons are found in the: nucleus
The number of protons determines: the identity of the atom/the element
The number of protons is called: the atomic number
Where you look to find the number of protons: periodic table(ex. boron is 5, barium 56, actinium 89, neon 10)
Protons are charged: positive charge
Neutrons are found in the: nucleus
Neutrons are charged: neutral(no charge)
They help protons by: stabilizing their repulsive charge(same charge repels) and stabilizing the nucleus
The mass of protons and neutrons are: 1 amu
Electrons mass is: 5.45 × 10^-4 amu(usually for practical purposes people just say it has 0 mass)
Electrons are charged: negatively
In a neutral atom: number of protons = number of electrons(net charge = 0)
Electrons are responsible for: keeping the atoms neutral, valence electrons interact with other atoms to form ionic compounds.
