Question

the element x on atomic number 16 form basic oxide the number of electron in X2 - Ion will be​

JUST EXPLAIN HOW TO DO IT.​

Answer 1

Explanation:

The atomic number of an element 'X' is 16. In the modern periodic table the element 'X' belongs to p− block, group 16 or VI A and third period period.

The element 'X' is sulphur with symbol 'S' with electronic configuration 2,8.6 in K,L and M shells respectively.

Answer 2

ELECTRONIC CONFIGURATION -

• The arrangement of electrons in the electronic orbitals of an atom or molecule.
• It is the electronic structure of atomic or molecular orbitals.
• The element 'X' with atomic number 16 will have an electronic configuration of 2, 8, and 6 in the different shells of an atom.
• The element with 16 electrons is SULPHUR with electronic configuration $1s^22s^22p^63s^23p^4$
• The valence shell 3p contains 4 electrons therefore it belongs to the p-block in the periodic table.
• It is placed in the 16th group of the modern periodic table based on the configuration of$3s^23p^4$.
• The metal reacts with air to form a metal oxide that is basic in nature.
• The electrons in$X^2^-$ or $S^2^-$will be 18 and it will gain two electrons to form an anion.
