Answer:

Answer is Below

Explanation:

According to , Since the last shell of an aluminum-ion has eight electrons, the valence electrons of aluminum ion (Al3+) are eight.

Answer:

Aluminum has an atomic number of 13. The electronic configuration of Al is 1s2 2s2 2p6 3s2 3p1. Al3+ has only 10 electrons so the configuration of Al 3+ is 1s2 2s2 2p6. The highest energy level is 2 so the number of electrons in the highest level is the valence electrons which is 8.

The characteristics of two different types of reactions are shown downwards
a_sh-v [17]

Answer:

Valence electrons are involved in Reaction B but not in Reaction A.

Explanation:

The description of reaction A in which protons are lost or gained by the atom of the element is a nuclear reaction. In nuclear reactions, the nucleons which are the protons and neutrons drives the reaction. No valence electrons in the orbiting shells are involved in this kind of reaction. During this type of reaction, an atom changes it identity to that of another.

Reaction B in which no identity change occurs is a chemical reaction. In chemical reactions bonds are formed by the atoms using the valence electrons that orbits round the central nucleus. The atoms remain the same but it chose to attain stability and an inert configuration by losing or gaining electrons.
