There are two shells in period 2 (that's why it's named like that)
The first can hold (max.) 2 electrons (1s2), the second holds 2+6 = 8 electrons (2s2 and 2p6) at maximum.
There are 18 elements in period 4 of the periodic table, corresponding to 4 shells.
see what period it is in on the periodic table it is in period 6, so therefore there are 6 electron shells or energy levels
potassium has 4 shells first shell has 2 second 8 third 8 fourth 1
7. It is in period 7, at the bottom of the periodic table.
Polonium has 6 electron shells.
if an element has 1 shell in its atom it is in period 1and so on... 2 shells=period 2 3 shells=period 3 4 shells=period 4 5 shells=period 5 6 shells=period 6 7 shells=period 7
Period number = no. of electron shells. Therefore neon has two shells.
all elements in a period all have the same amount of shells example: all elements in period 1 has only 1 shell all elements in period 2 has 2 shells so the period number is the same as the number of shells in that period
There are 18 elements in period 4 of the periodic table, corresponding to 4 shells.
see what period it is in on the periodic table it is in period 6, so therefore there are 6 electron shells or energy levels
Phosphorus in is 3rd period. So it has 3 electron shells.
Oxygen is on period 2 whereas sulfur is on period 3. Therefore, sulfur has more electron shells than oxygen.
potassium has 4 shells first shell has 2 second 8 third 8 fourth 1
Group 2 Period 3
The number of electron shells depends on the noble gas. The number of shells will be equal to the period in which the noble gas is present.
7. It is in period 7, at the bottom of the periodic table.
Polonium has 6 electron shells.
