2nd: 2353 kJ/mol

3rd: 4621 kJ/mol

4th: 6223 kJ/mol

5th: 37832 kJ/mol

6th: 47279 kJ/mol

7th: 55261 kJ/mol

8th: 69875 kJ/mol

You would do 1500/4 and the answer is 375

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
