Why is K2O scientific name called potassium oxide?

Answer 1

because the K stands for potassium and the O stands for oxygen and because when there is a metal and a non-metal and there are only two elements you put the metallic element first, the name of the non-metal is shortened and the suffix '-ide' is added to the shortened name e.g K2O = potassium oxide

Answer 2

The scientific name for K2O, potassium oxide, reflects the chemical composition of the compound. It consists of potassium (K) and oxygen (O) atoms in a 2:1 ratio, hence the name potassium oxide. This naming convention is based on the elements present in the compound and their respective ratios.
