Does anyone know what ionic and covalent bonds are and how do u draw them or work out how many electrons to put in the shells depending on which element it is?

Ionic bonds are made by a transfer of electrons. Covalent bonds are made by sharing electrons.

Explanation:

For ionic bonds, use the group number to help you determine how many electrons an element can give or receive (Group 1 gives 1 electrons, group 2 gives 2 electrons, group 3A gives 3, group 5A receives 3, group 6A receives 2, and group 7A receives 1).

Covalent bonds have to be worked out using the total number of valence electrons and the octet rule.

answer: i would say b.
