What group 2 element has the smallest radius?
Beryllium (Be) is the group 2 element with the smallest atomic radius. This is due to its higher nuclear charge relative to its size, which results in a stronger attraction between the nucleus and the electrons, pulling them closer. As you move down the group, atomic radii increase because additional electron shells are added, outweighing the increase in nuclear charge.
Which element within period 2 contains the greatest nuclear charge?
The element within period 2 with the greatest nuclear charge is neon. This is because neon has more protons in its nucleus compared to the other elements in period 2, giving it the highest nuclear charge.
The atomic charges of each group?
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.
What is the effective nuclear charge for the atom Mg?
the effective nuclear charge on barium is 2.
What is the charge on an ione of group 2 element?
+ve 2
What is effective nuclear charge of beryllium?
1.5
Which element within period 2 contains the greatest nuclear charge?
The element within period 2 with the greatest nuclear charge is neon. This is because neon has more protons in its nucleus compared to the other elements in period 2, giving it the highest nuclear charge.
Why are the group 1 and group 2 metals the least electronegative?
Group 1 and Group 2 metals have larger atomic radii and low effective nuclear charge, making it easier for them to lose electrons rather than gain them. This results in lower electronegativity values for these metals.

How is the ionic charge of a group 1A 2A or 3A ion determined?
The ionic charge of a group 1A, 2A, or 3A ion is determined by the number of electrons lost or gained to achieve a full valence shell. Group 1A ions lose 1 electron to attain a +1 charge, group 2A ions lose 2 electrons for a +2 charge, and group 3A ions lose 3 electrons for a +3 charge.
How is the charge on a simple cation related to the group of a main group element?
Sodiumis in group 1 and its cation is charge +1. Calcium is in group 2 and the cahrge on its cation is +2. etc.
What is the charge on an ione of group 2 element?
+ve 2
What is the charge for a group six ion?
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
What charge would an ion have based on its group?
1: 1+ 2: 2+ 13: 3+ 14: 4+/- 15: 3- 16: 2- 17: 1- 18: Neutral Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
What is the group in the periodic table for cations whose charge is 2?
Group 2, alkali earth metals.
What is the charge of oxygen and how would you find the charge of an element using only the periodic table?
Oxygen typically has a charge of -2. To determine the charge of an element using only the periodic table, you can look at its group number (columns) for main group elements or its oxidation state for transition metals. The charge is often determined by the number of valence electrons an element gains or loses to achieve a stable electronic configuration.
