Question

when an element in the first group of the periodic table reacts with an element in the seventh group what is the type of bond that is likely to be formed?

Answer 1

Answer:

i do not know the answer you know so tell me

Answer 2

The type of bond likely to be formed is a covalent bond.

• The elements in the first group of periodic table have high electropositivity. They have more ionisation potential compared to other groups.
• The elements in the seventh group are halogens. They have very high electronegativity.
• The first group has one electron in its valence shell and the seventh group needs one electron to complete its valence shell.
• Since both need to either give away or aquire one electron, they share their electrons and form a covalent bond. This may either be a non-polar covalent bond or a polar covalent bond.
• Examples of such bonds are HCl and NaCl.
