Not all but yes most of them.

#### Explanation:

Most of the metal Oxides , carbonates and Hydroxides are basic in nature.

Some exceptions are there :-

1) $O s {O}_{4}$ $, {V}_{2} {O}_{5}$ $, C r {O}_{3}$ These type of metallic oxides are acidic in nature because of the large Oxidation number of the Metal.

2) $A {l}_{2} {O}_{3}$ $, P b O$$, Z n O$ These are Amphoteric oxides.
