An element ‘M’ with electronic configuration 2 8 3 combines separately with `Cl^-`, `SO_4^(-2)` anions. Write the chemical formulae of the compounds formed. Predict with the suitable reason the nature of the bond formed by element ‘M’ in general. How will the electrical conductivity of the compounds formed vary with respect to ‘M’?

An element 'M' with electronic configuration (2,8,2) combines separately with (NO_(3))^(-),(SO_(4))^(2-) and (PO_(4))^(3-) radicals. Write the formula of the three compounds so formed . To which group and period of the Modern Periodic Table does the elements 'M' belong ? Will 'M' form covalent or ionic compounds ? Give reason to justify your answer.

Give the formula of the compound formed by combinning Fe^(2+) and Cl^(-)ions

Write the formula of the product formed when the element A (atomic number 19) combines with the element B (atomic number 17) Draw its electronic dot structure. What is the nature of the bond formed ?
