What is a charged particle resulting when an atom loses one or more electrons? And what is a common compound with 2 hydrogen and 2 oxygen atoms? Please respond ASAP

H2O2 is hydrogen peroxide.

An atom with too few or too many eletrons is called an ION, it is a positive ION if the atom has lost an electron, it is a negative ION if it has gained an electron.

Welcome to the Forum. Look up ION on Google or Wiki for more information if you need it.
