What is Al3+ electron configuration?
Answer and Explanation: The electron configuration of an aluminum ion, Al3+, is 1s2, 2s2, 2p6.
How many protons does Al 3+ have?
Daniel Nelson. The charge of an aluminum ion is typically 3+. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons.

Is Al 3O2 → 2Al2O3 balanced?
We can then change the coefficient of 2 in front of the aluminum to a 4. Finally we have a balanced equation: 4Al + 3O2 –> 2Al2O3 . There 4 aluminums on each side and 6 oxygens on each side!
How many protons and electrons does al 3 have?
The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons. Aluminum then has three excess protons so the charge of a base aluminum ion is 3+. That's the quick answer regarding how aluminum's charge is 3+.
How many neutrons does al 3 have?
14 The number of protons in Aluminium is 13. The 27 means the atomic mass is 27 . The number of protons plus the number of neutrons is 27. That means the number of neutrons is 27–13=14.
What does Al3+ mean?
Aluminium Description. Aluminium(3+) is an aluminium cation that has a charge of +3. It is an aluminium cation, a monoatomic trication and a monoatomic aluminium.
How many electrons are present in the Al3+ ion?
Clearly, there are 10 electrons associated with a single Al3+ ion. We don't need any chemistry to make this determination. The atomic number specifies the number of positively charged particles in the atomic nucleus.
