When you move down a family of elements why the size increases?

It is because when you move down, the number of electrons increases. When the number of electrons increases, it calls for more energy levels to fit these electrons.
With each additional period, an additional energy level is occupied. This additional energy level is farther from the nucleus than the previous energy level, so the atoms increase in size.

What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
How do the metallic properties of the elements change as you move from left to right on the periodic table?
Metallic character decreases as we move across a period. The electronegative character increases as we move across a period. So the element across the period will be non mettalic in nature.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
Why does the metallic character of the elements in a family increase as you move from top to bottom in ther periodic table?
in groups metallic character increases with atomic number because each successive element gets closest to Fr
What happens to the size of an atom as you move top to the periodic table?
Size typically increases going down a group due to an increasing number of electron shells, where the inner shells reduce the attractive forces of the nucleus and repel the electrons in the outer shell .
What do elements in each group or family have in common?
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
What is the similarity and the difference between the two elements found in the same group?
As we move down the group ,the electrons in the valence shell remains constant but the number of shells increases by one.size of the element increases down the group .elements are more electro-positive as we move down the group so elements at the bottom are more electro-positive than those at the top.as the size of the elements increases the nuclear charge on the elements decreases.due to less nuclear charge shielding effect decreases down the group.
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What do you notice about the number of orbitels as you move from down a family in the periodic table?
the number of orbitals increases by one for each period.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
Do elements on the periodic table increase in electronegitivity as you go left to right or up and down?
Electronegativity increases as we move from left to right on the periodic table.
As you move up to down in a column of the periodic table elements have what?
It increases because as you move down a family / column in a periodic table, the amount of protons and electrons increase, creating more rings of electrons on the atom, therefore with more rings, the size of the element increases.
As you move down a group or family on the periodic table which of the following isnt true?
A)The number of energy levels increases B)The atomic number increases C)The number of valence electrons increases Those are the answer choices ^
Why does size of f block elements increase as you move across the periodic table?
because when you move it . it increases in size
Are elements in the front rows more metallic than the elements in the last row?
Metalic Nature DECREASES as you move across a period (horizontal rows) from left to right. It INCREASES as you go down a group (the vetical collums)
What are some boron family similarities?
They are all poor metals (except for boron, which is a metalloid). The reactivity decreases as you move down the group. The atomic radius increases as you go down the group.
