The increase in radius at the beginning of each new period is due to the expansion of the artery walls to accommodate the increased blood flow during systole (when the heart contracts and pumps blood into the arteries). This expansion allows the artery to store more blood temporarily before it is pushed further down the circulatory system during diastole (when the heart relaxes).
What else can I help you with?
Why are the radii changing as you move down the table within a column?
Radii generally decrease from left to right along each period (row) of the table, from the alkali metals to the noble gases; radii increase down each group (column). The radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period
Why does radius increase if you go down a group?
Because as you go down a group, with each additional period, an additional energy level is added. Each additional energy level is farther from the nucleus than the previous energy level.
Why atomic radius remains almost uncharged as you move through period 2 from group 14 to group 18?
The increase in nuclear charge as you move across period 2 from group 14 to group 18 is offset by a simultaneous increase in the number of electrons, resulting in the atomic radius remaining relatively constant. The additional electrons in each successive element are added to the same energy level (n=2 in period 2), which keeps the average distance of the outermost electrons from the nucleus consistent.
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.
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.
The number of valence electrons increases with increase in what from the beginning to the end of period 2?
The number of valence electrons increases with increase in atomic number from the beginning to the end of period 2. The maximum number of valence electrons possible in any outermost shell is 8.

Why does radius increase if you go down a group?
Because as you go down a group, with each additional period, an additional energy level is added. Each additional energy level is farther from the nucleus than the previous energy level.
What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
Does the atomic radius decrease as you move up a group and across a period from left to right on the periodic table?
the atomic radius decreses from left to right in periodic table due to increase in the number of succesive element the electrons of the outermost shell are more attracted towards nucleus and the atomic radius or atomic size decreases.
Why atomic radius remains almost uncharged as you move through period 2 from group 14 to group 18?
The increase in nuclear charge as you move across period 2 from group 14 to group 18 is offset by a simultaneous increase in the number of electrons, resulting in the atomic radius remaining relatively constant. The additional electrons in each successive element are added to the same energy level (n=2 in period 2), which keeps the average distance of the outermost electrons from the nucleus consistent.
When lose electrons does radius increase?
No, the radius decreases. Electrons, being negative, repel each other. The more electrons there are, the farther away they have to get from each other. The fewer there are, the less total force there is, and the closer they can be.
What makes the atomic radius change along a period in the periodic table?
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
What is a series of equal payments to be received at the beginning of each period for a finite period of time called?
Annuity due.
Within a period what happens to the atomic radius you go down the column?
The atomic radius generally increases as you move down a column in the periodic table. This is because each successive element has an additional energy level, leading to larger orbits for the electrons and an overall increase in atomic size.
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.
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.
