This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The first shell can hold two, the second and beyond can hold 8.
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The L shells holds only 8 electrons. The M shell holds 8 electrons. However, it can hold up to 18 when the atomic number increases.
Your question is a bit vague, but if you are enquiring about the first electron shell in an atom, it holds a maximum of two electrons.

The first shell can hold two, the second and beyond can hold 8.
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
the O major shell can hold 1 electron
The hydrogen atom (1H) has only 1 proton and 1 electron (you probably think at this electron).
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
