Question

two element X and y have atomic number 12 and 16 represent imali to which period of the modern periodic table do this this two element belong what type of blood will be formed between then they were also give the chemical formula of the compound formed

Answer 1

Answer:

atomic no. of x = 12 => it is magnesium

so, its electronic configuration = 2,8,2

here, it has 3 shells so, it will belong to 3rd period

now, atomic no. of y = 16 => it is sulphur

it's electronic configuration = 2,8,6

it has 3 shels so, it belongs to 3rd period.

now, charge of magnesium = 2+

and charge if sulphur = 2-

so, formula of compound = MgS
