Which is the smallest atom?

The smallest atom is hydrogen.

Are atoms electrically charged particles?

An electron is a sub-atomic particle, not an atom. But it is electrically charged (it has a charge of minus one). The simplest atom, the hydrogen one isotope, has just one proton and one electron. An electron is a part of an atom. Every atom is composed of protons and electrons. Usually there are also neutrons. Protons are positively charged +1 and electrons are charged -1. Neutrons are neutral. When the number of protons and electrons are equal the atom is neutral. When an atom has an unequal number of protons and electrons it is charged either - or +. More electrons make it - and more protons make it +. In both cases the atom is called an ion.

What are the two lightest gases in the universe?

In our known universe, hydrogen then helium. But this may change with further exploration.
