What is the name of this element

Carbon

Explanation:

This elelemnt is carbon because it has 6 protons. The number of electrons determines the type of element. Only carbon can have 6 protons. The mass number is 13. 6 protons + 7 neutrons = mass of 13. This is an isotope of carbon. This isotope is called carbon-13.

protons = positive charge (in the nucleus) tells what the element is

neutrons = neutral charge (in the nucleus)

electrons = negative charge (orbits the nucleus)

i think 4.44 moles

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
