Question

Complete the table below, with elements E, F, G, and H, such that element E is an inert gas having electronic configuration 2,8.

Elements	Atomic number	Electronic configuration
E	Z	2,8
F	Z-1	…………………
G	Z+1	…………………
H	Z+4	………………….

Answer 1

Electronic configuration — The distribution of electrons in a given shell or orbital is considered an electronic configuration

• It also helps to predict whether the elements are metal, Non-metal, metalloids, and noble gas
• It is based on the atomic number{Z }
• Atomic number {Z } of E element E is 10

Elements	Atomic number	electronic configuration
E	Z	2,8
F	10 - 1	2,7
G	10 +1	2,8,1
H	10 + 4	2,8,4
