Write down the formulas and indicate the type of chemical bond for the following substances: a) table salt; b) silver;

Write down the formulas and indicate the type of chemical bond for the following substances:
a) table salt;
b) silver;
c) magnesium;
d) carbon dioxide.

a) table salt; NaCl, ionic bond, because it is formed by atoms of metal and non-metal elements.
b) silver; Ag, metal bond, because it is formed by the atoms of the metal element.
c) magnesium; Mg, metal bond, because it is formed by the atoms of the metal element.
d) carbon dioxide; CO2, covalent polar bond, because it is formed by atoms of non-metallic elements with different electronegativity.
e) water; H2O, covalent polar bond, because it is formed by atoms of non-metallic elements with different electronegativity.
f) nitrogen. N2, a covalent non-polar bond, since it is formed by atoms of the same element.
