The element aluminum has 13 protons. It will have 13 electrons in its neutral state, though aluminum loans out electrons to form bonds. Under these circumstances, it will have 10, 11 or 12 electrons.
The only stable isotope of aluminum (aluminum-27), and basically the only one found in nature, has 14 neutrons in it. (There have been, however, investigators who report a trace of Al-26, which has 13 neutrons in it.) We should note that we have synthesized a number of isotopes of aluminum in the lab. Links can be found below for more information.
The number of protons in an atom is called the atomic number. Therefor, aluminium has 13 protons. The mass number is the number of protons and neutrons. Therefor, (27-13=14) aluminium has 14 neutrons. The number of protons is equal to the number of electrons, Therefor, aluminium has 13 electrons.
3 valance electrons,13 electrons,13 protons,14 neutrons
The neutral atom of molybdenum has 42 electrons.
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
Aluminum has 3 valence electrons.
No, the valance electrons determine the charge, the atomic number is determined by the number of protons. Generally, electrons are equal to protons, but in ions it is different, so use protons.

it has 19 electrons and 19 protons and 20 neutrons
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
Nitrogen14, has 7 protons, 7 electrons and 7 neutrons.
A calcium atom typically has 20 protons, 20 electrons, and approximately 20 neutrons.
The neutral atom of molybdenum has 42 electrons.
The number of neutrons is variable.

Aluminum has 3 valence electrons.
13 protons would indicate the element is aluminum, Al. It has the electron configuration of1s2 2s2 2p6 3s2 3p1. In the 3rd energy level, there are 3 electrons, thus it has a total of 3 valence electrons.
as far as i know aluminum is a molecule not an atom. The aluminum atom has a valence of 3, what its chemical structure is depends on what it combines with.
A neutral atom of aluminum has 3 valence electrons.
