D) network
4) what type of bonds are present in magnesium metal
A) covalent
B) ionic
C) metallic
D) van der waals

Answer 1

1) A 2) A 3) A 4) C: Mg lies in group 2: Alkali Earth Metals, it is a metal


4) C

Answer 2

An ionic bond is formed between a metal and a non-metal that differ greatly in electronegativity values. In an ionic bond formation, electrons are transferred from the least electronegative element, metal to the element having greater electronegativity, non-metal. The metal which transfers electrons has lower ionization energy than the non-metal.

So, the correct answers will be

1) B) lower electronegativity value and C) lower ionization energy

2) A) Ionic bond

3) A) ionic

4) C) metallic
