500

Without seeing the periodic table, state the number of electrons, neutrons and protons of Bromine.

e = 35

p = 35

n = 45

500

Explain why an ionic bond has a higher melting point compared to a covalent bond.

Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions. It takes a lot of energy to break the many strong bonds, thus the higher melting point.
