Atomic size generally increases as you go down a group

∙ 9y agoA period in a Periodic Table is a horizontal row of elements. Across any period, trends in ionization energy, electron affinity, and electronegativity, and atomic radius may be noted. From left to right across a period, atomic radius usually decreases while atomic mass, or weight will always increase.

∙ 14y agoYes as the number of electron, protons and neutrons increase across (and down) a period so does the size of an atom.

How does atomic size generally go on the periodic table?
Atomic radius generally decreases as you go from left to right in the same period. Atomic radius increases as you go down the same group.
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
What is the periodic trend for atomic size from top to bottom in a group?
The size of an atom refers to its atomic radius. Atomic radius generally increases down a group. This is because the number of energy levels increase down a group with each additional period. Each of the subsequent energy levels are larger than the last, increasing the distance of the electrons from the nucleus, which increases the atomic radius.Atomic radius generally decreases across a period. This is because electrons are being added to the same energy level at the same time that protons are being added to the nucleus. This creates a stronger force of attraction by the nucleus for the electrons, which pulls the electrons closer to the nucleus, decreasing the atomic radius.It is important to note that the periodic trends are not laws. There are exceptions to the general trends in both the representative elements and the transitional elements.
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..
Which element in group 17 has the largest radius?
Atomic size increases down a group as the energy level (or shell) increases. So Astatine will have the largest size (radius) in group 17

What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
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.
What happens to the atomic structure as you go down any group?
Down a group, the atomic size (energy level / shells) increases.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.

How does size change in a period and in a group?
Atomic size decreases across a period as the effective nuclear charge increases. Atomic size increases down a group as the energy level (shells) increases.
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.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen
What happens to the size of the halogen atoms as you go down the group?
atomic number increases
Which trend decreases for metals down a group atomic radiusreactivity or melting point?
Melting points generally decrease as you go down a group for group I and group II metals. This does not apply to the transition metals. Reactivity of metals increases down a group due to a larger size and less effective charge between the nucleus and valence electrons. Atomic radius increases due to a higher principle number of electrons.
