What else can I help you with?
What determine an atoms size?
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
How does the presence of core electrons affect the atomic radius of elements?
When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
Why does the atomic radius change as you move across the periodic table?
As you move across a period in the periodic table from left to right, the atomic radius decreases due to the increasing positive charge of the nucleus. This increased nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus and resulting in a smaller atomic size. Additionally, since electrons are added to the same energy level without significant increase in shielding, the effective nuclear charge felt by the outermost electrons increases, further reducing the atomic radius.
What is the charge of a barium atom that has lost two electrons?
it neets to loose 2 electrons to have a full outer shell.
What accounts for the fact that the radius of f is smaller than the radius of li?
Increasing positive nuclear charge

What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius

What occurs to the radius when an atom loses an electron?
The negative ionic radius is larger than the neutral atomic radius

it neets to loose 2 electrons to have a full outer shell.
Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
What is the ionic charge of radius?
A radius is either a geometric concept or a bone in the forearm. In either case, it does not have an ionic charge.
How does the radius of a cone compared to the radius of a cylinder?
In both cases, the radius can be any positive number.
