If the mass number of an atom is 29, and it has 13 protons and 13 electrons, the identity of this atom is Aluminum.
<h3>What is an atom?</h3>
An atom is the smallest indivisible particle of an element which still retains its chemical identity.
An atom consists of a nucleus surrounded by electrons. The nucleus is made up of protons and neutrons.
The identity of a chemical element is determined by its electron and proton number, which is the same for a neutral atom.
According to this question, the atom of an element has 13 protons and 13 electron. This suggests that the atom is that of Aluminum.

Answer:
atomic orbital
Explanation:
Atoms are made of three sub-atomic particles, electron, proton and neutron.
Protons and neutrons are present in the core of the atom in a very small zone called nucleus. Nucleus is positively charged.
Electrons are present around the nucleus. Electrons present outside the nucleus are also termed as electron cloud. Region outside the nucleus where probability of finding an electron is maximum is termed as atomic orbital. Four basic types of orbitals are present around the nucleus which are
s-orbital
p-orbital
d-orbital
f-orbital
Electrons present in same orbitals have same energy. Therefore, term is atomic orbital.
OK so basically my friend Protons electrons and neutrons form an atom so that's basically it's building structure.
