How are electrons arranged in elements with atomic numbers 1 through 10?

Each shell can hold a maximum number of electrons. Moving through the elements in the periodic table, each atom has one more electron than the last because the number of electrons is the same as the atomic number . Electrons occupy the shells in order, starting with the shell that is nearest the nucleus .

Explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
