Question

An element having an atomic number 14 has "x" valence electrons and the element with atomic number 6 has " y" valence electrons . What will the value of x-y?

Answer 1

Answer:

The value of x - y is 0

Step-by-step explanation:

Element with Atomic Number 14 is Silicon (Si)

The electronic configuration of Si is

2, 8, 4

The number of valence electrons = no. of electrons in the outermost shell

Therefore, the number of valence electrons = 4

or x = 4

Element with Atomic Number 6 is Carbon (C)

The electronic configuration of C is

2, 4

The number of valence electrons = 4

or y = 4

Therefore, x - y = 4 - 4 = 0

Answer 2

Answer:

The answer is 0
