the atom has 6 protons and 6 electrons the atomic number of (z)of the atom is 6 the mass number (A) of the atom is 12 the chemical symbol for this atom is C.

# data[].attributes.body
Atomic Number : Number of Protons

Mass Number : Protons + Neutrons

Net Charge : Protons - Electrons

# data[].attributes.body
Charge:

Protons are positive, electrons are negative, neutrons have no charge.

Mass:

Protons and neutrons are heavy (about the same), electrons are much lighter.

Position:

Protons and neutrons are packed in the nucleus, while electrons move around it.

Simple way to remember:

Proton = Positive

Neutron = No charge

Electron = External (outside nucleus)

🔹 Carbon (C)

Atomic number (Z) = 6

Mass number (A) = 12

Protons = 6

Electrons = 6

Neutrons = 12 − 6 = 6

🔹 Nitrogen (N)

Atomic number (Z) = 7

Mass number (A) = 14

Protons = 7

Electrons = 7

Neutrons = 14 − 7 = 7
