The valency does not (or tends not to) vary going up and down a group. It varies going across a period.

How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
How does the strength of the reaction with water vary as you move down the group of alkali metals?
as you go down there are more electrons on the outer shells which makes them more reactive when in contact with water
What body parts are used in humping?
The two privets in sex like the vagina and the pinus. The man gets on her and starts moving up and down vary fast
What do the 20 amino acids vary in?
The amino acids vary in the side groups, usually designated by "R" on the chemical structures for amino acids. The invariant parts are the amino group (NH2-), central (-CH-) group, and the carboxyl (-COOH) group. Connected to the central carbon on the (-CH-) group is a side group which is part that varies.
How does valency of elements vary going down a group?

How does the size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
How does valency of element with respect to hydrogen vary in a period?
in a period from left to right valency of elements with respect to hydrogen increases from 1 to 4 and then decreases upto 1 and with respect to oxygen increases from 1 to 7.
How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
When moving down a group ( family) in the periodic table the number of valence electrons?
When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.
How does the strength of the reaction with water vary as you move down the group of alkali metals?
as you go down there are more electrons on the outer shells which makes them more reactive when in contact with water
How do the sizes of atoms vary within a group (family)and explain why?
The atomic radius increase down in a group; the cause is the lower attraction from the nucleus atoms with increased bigger atomic mass.
How much does international moving cost?
International moving prices vary. It really depends on what you are moving, where you are moving to, and where you are coming from. Prices will always be different.
What body parts are used in humping?

Comment on the trend in the boiling points of the Noble gas elements and why do boiling points vary in this manner.?
According to the trend, the boiling point of the noble gases decreases down the group, as you know the number of shells increases down the group but the number of valency electrons remains the same. the further away the nucleus is to the outer electron, less the attraction. Therefore, resulting in less energy needed to change the state of the element which brings us to the conclusion of decrease in the boiling points of noble gases down the group. I hope it helps Cheers mate !
Are girls in gangs?
Yes, but their roles vary from group to group.
