Question

two element A and B have 14 and 9 electrons in M- and N shells, respectively. then the ratio of their atomic number

Answer 1

Answer:

24 : 37

Explanation:

element A have 14 electrons in m shell

atomic no. = 14 + 8 + 2 = 24

element B has 9 electrons in N shell

atomic no. = 9+ 18 + 8 + 2 = 37
