Question

3. If aluminum losses three electrons, how many electrons will it have in its outermost electron orbit?

4. What type of compounds, metals or non-metals, will gain electrons and become negatively charged? Explain why this will occur.

5. What particles in an atom are responsible for bonding?

Answer 1

Answer:

Explanation:

• If aluminum losses three electrons, how many electrons will it have in its outermost electron orbit?

=Aluminium is located in period 3, group 13, and has an atomic number equal to 13 . This tells you that the electron configuration of a neutral aluminium atom must account for a total of 13 electrons. Now, when aluminium forms 3+ cations, Al3+ , it loses 3 electrons from its outermost energy shell.

• What type of compounds, metals or non-metals, will gain electrons and become negatively charged? Explain why this will occur.

=When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds. A neutral chlorine atom has seven electrons in its outermost shell.

• What particles in an atom are responsible for bonding?

=Electrons play a major role in all chemical bonds. There is one type of bonding called electrovalent bonding (ionic), where an electron from one atom is transferred to another atom. You wind up creating two ions as one atom loses an electron and one gains one
