How many electrons are in a aluminum atom?

Answer 1

An aluminum ion has a charge of +3. It is not a neutral atom. It has a positive charge, therefore electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. However, you must take away 3. THERE ARE 10 ELECTRONS IN AN ALUMINUM ION.

Answer 2

Aluminum has 13 electrons in a neutral atom. The 1S2, 2S2 and 2P6 shells are full, and so is the 3S2. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two "semi-valence" electrons which can be loaned out. And what'll you bet that it would like to loan that electron out? Or the other two? You're right, it would like to do that. It's oxidation states are +1, +2 and +3.
It has 13 electrons and 13 protons because it is the 13rd element of the Periodic Table.

Answer 3

An aluminum atom has 13 electrons. This is equal to the atomic number of aluminum, which is 13.

Answer 4

Aluminium is a metal element. There are 13 electrons in a single atom.

Answer 5

13 electrons, 13 protons, atomic number 13

Answer 6

10

1s2 2s2 2p3 3s2 3p1

With the formation of the ion, the electrons in the third energy level are lost, leaving the aluminium (yes, aluminium) ion with a +3 charge.

Answer 7

Aluminum's atomic number is 13. That means it has 13 protons, which are positively charged. To neutralize this charge, aluminum is also found with 13 electrons.

Answer 8

There are 13 electrons in Aluminum.

Answer 9

Aluminium has 13 electrons.

Answer 10

The neutral atom has 13 electrons.
