# What is the basic formula of a binary compound?

Jul 28, 2017

$A + B \to A B$.

#### Explanation:

Binary compounds are compounds that were made from two different elements.

They have a formula of $A + B \to A B$. They don't equal, instead, they yield (the arrow).

Some examples include:

$N a + C l \to N a C l$ => Sodium chloride
$2 P + 3 {H}_{\text{2" -> 2PH_"3}}$ => Phosphorus trihydride
$2 S n + {O}_{\text{2}} \implies 2 S n O$ => Tin (II) oxide

Hope this helps :)
