Question

the outermost electronic configuration of an element is 3s² 3p⁴.Write the a) complete Subshell electronic configuration b) atomic number c) metal/non-metal d) valency

Answer 1

a. complete electronic configuration:

$\tt 1s^22s^22p^63s^23p^4$

so the above mentioned configuration is the complete configuration of sulphur

b. the atomic number can be easily calculated by counting the number of electrons :

2+2+6+2+4 = 16

the atomic number of 16 is of sulphur

c. sulphur Is a non - metal

d. the valency of sulphur is 2 and the number of valence electrons of sulphur is 6.

hope this helps!!️
