Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.

What is the process that results in the increase of atomic number?
The number of energy levels increase within a group. Therefor the atomic radius increases. So the atomic volume also increases.The atomic radius also increases in a group.For metals, reactivity increases down the group. For non-metals, reactivity decreases down a group.
What is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
Does Francium have the largest atomic radius on the periodic table?
Francium has the largest atomic radius in Group 1 of the Periodic Table.
What element is in group 1 and has a higher atomic number than chlorine but a lower atomic number than bromine?
It is K, or Potassium, which atomic number is 19, which is greater than 17 and less than 35, and in group 1 of the periodic table, which is the alkali metals.
What element in group one has a higher atomic number than chlorine but lower atomic number than bromine?
It could be potassium(K)
Which of these describes atomic radii as one moves from top to bottom within a group?
The atomic radius increases from top to bottom within a group.
How does the ionization energy vary with atomic number within the group?
Ionization energy decreases with the rise of atomic number in a group of periodic table.
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.

Why does the ionization energy tend to decrease from top to bottom within a group?
there is an increase in atomic number and atomic size down the group due to addition of extra shells.this increase in the atomic size overcomes the effect of an increase in the nuclear charge.Therefore ionisation energy decreases with an increase in atomic size i.e.,it decreases as one moves down a group..
What trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
What trend can be seen in the mass of atoms or elements within a family?
Within a family or group of periodic table the atomic mass increases from top to bottom.
How does the physical state of a metal change as the atomic number increases?
sticking to increasing at no within group: more soft
What is the term for a group of subjects that receives all variables except for the independent variables in an experiment?
control group
What are the general trends andpatterns within the periodic table?
Atomic radius increases down the group. It decreases along a period.
How does electrons shielding affect atomic size as you move down the group?
Shielding affect acts as a barrier for proton to attract electrons, therefore the electrostatic force (the which attracts electrons to protons) becomes much less and electrons become further away from the nucleus of the atom. Because of this, the atomic size increases as you move down the group.
