the element x on atomic number 16 form basic oxide the number of electron in X2 - Ion will be
Answers
Answer:
18 electrons
Explanation:
As in it the element x is gaining 2 electrons the no of electrons in it changes from 16 to 18.
please mark as brain listed
Answer:
the number of electron in X2 - Ion will be 18.
Explanation:
In the periodic table, the element having 16 electrons is sulphur. The atomic mass of sulphur is 32 u. When an atom receives electrons, negative charge is developed on it. The number of negative charges is equal to the number of electrons received by the atoms. If an atom gains one electron , one negative charge is developed on it. When an atom loses electrons, positive charge develops on the atom.
In this atom 2 negative charge is developed on the atom, which means two electrons are accepted. So, the total number of electrons would be 18.
