Question 1

ELECTRON SHELL RULES:

Answer 1

1) ELECTRONS ALWAYS OCCUPY SHELLS (ENERGY LEVELS)
2) THE LOWEST ENERGY LEVELS ARE ALWAYS FILLED FIRST
3) ONLY A CERTAIN NUMBER OF ELECTRONS ARE ALLOWED IN EACH SHELL

Question 2

WHAT ARE THE. NUMBER OF ELECTRONS ALLOW IN EACH SHELL

Answer 2

2ND SHELL: 8
3RD SHELL: 8

Question 3

HOW TO CALCULATE THE ELECTRONIC CONFIGURATION OF NITROGEN

Answer 3

SINCE NITROGEN HAVE SEVEN ELECTRONS
AND THE 1ST SHELL NEEDS TO HAVE 2 ELECTRONS
THAN THE 2ND SHELL IS LEFT WITH 5 ELECTRONS

ELECTRONIC CONFIGURATION OF NITROGEN IS: 2, 5

Question 4

YOU CAN ALSO WORK OUT THE ELECTRONIC CONFIGURATION OF AN ELEMENT FROM ITS…

Answer 4

PERIOD AND GROUP
