all the elements in period 1 have one energy level, all the elements in period 2 have two energy levels, all the elements in period 3 have 3 energy levels... and so on
In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.
The number of shells define the period. The elements of the same group has same number of shells.
All elements in the same group have the same number of valence electrons.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
Period 2.
The time period may not affect the correlation coefficient at all. If looking at the correlation between the mass and volume of steel objects, time is totally irrelevant. The effect of the number of variables depends on whether or not the extra variables are related to ANY of the variables in the equation.
An elements period is determined by the number of electrons it has in its outer shell.
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
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
In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.
the number of protons
Number of Electrons.
Number of protons.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
The period number is equal to the number of energy levels. Elements of period 3 have 3 energy levels. Na,Mg,Al,Si are few elements in the period 3.
the rows of elements on the preiodic table are called the period. the period tells you the number of electron shells
all elements in one period have the same number of energy levels
