Let's address each question one by one.

Question 1: How many valence electrons do a magnesium atom and a chlorine atom have?

  • Magnesium has two valence electrons and Chlorine has seven.

So the correct response is:

  • Magnesium has two valence electrons and Chlorine has seven.

Question 2: Predict as to the type of bonds formed between magnesium and chlorine.

  • Magnesium and chlorine form ionic bonds. This is because magnesium donates its two valence electrons to chlorine, leading to the formation of oppositely charged ions (Mg²⁺ and Cl⁻).

So the correct response is:

  • Magnesium and chlorine form ionic bonds.

Question 3: Predict the number of Magnesium that will bond with the number of Chlorine.

  • Since one magnesium atom can lose two electrons and one chlorine atom can gain one electron, one magnesium atom will bond with two chlorine atoms.

So the correct response is:

  • One magnesium will bond with two chlorine.

Question 4: Why do magnesium and chlorine bond the way they do?

  • Magnesium and chlorine bond in this way because they each want to have a stable configuration of eight valence electrons (the octet rule). Magnesium aims to lose two electrons to attain a stable electron configuration, and chlorine aims to gain one electron.

So the correct response is:

  • They each want to have a stable configuration of eight valence electrons.
