What are the period and group trends in electronegativites?
The trends from left to right in a period increase (nuclear charge), and moving down a group decreases (shielding).
Physical properties within a period are more alike than physical properties within a group true or false?
False. Properties within a group are more alike than properties within a period.
Is a physical properties within a period more alike than physical properties within a group?
group is more alike
Are Physical properties within a period are more alike than physical properties within a group?
No, the physical properties within a group are more alike than those of a period. This is because all elements in a group share the number of valence electrons.
Are properties within a group are more alike than properties within a period?
true
Which element has the biggest shielding?
When a period of elements are considered, the element in group 18 has the highest shielding effect.

How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What is a period property?
The properties which change regulary from top to bottom in a group and from leaft to right a period are called periodic property.
Why Na has higher shielding effect than Li?
The reduction in the force of attraction between the nucleus and the valance electrons by the electrons present in the inner subshells is called shielding effect.As you move from top to bottom in a group number of electronic shells increase so the number of electrons in the inner shells also increases. As a result shielding effct increases.Therefore Na will have higher shielding effect than Li as it comes after Li in the group.
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
