Look for the highest numbered atom in the group: radium.
Also barium has an empirical radius similar to the radius of radium: 215 pm.
Atomic Size is the going across any period, atomic radius is decreasing in size due to the increase in the number of electrons is attracted toward the nucleus. Going down any group, there are a large increase in atomic size. The size of an atom depends on where the electrons are distributed outside the nucleus.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
The largest Bohr orbit in a uranium atom is the outermost electron orbit, also known as the valence shell. Uranium has 92 electrons, so the valence shell would be the 7th energy level (n=7) as per the Bohr model.
An atom of boron-10 (10B) has 5 electrons. The atomic number of boron is 5, indicating the number of protons and electrons in a neutral atom.
It is the rubidium metal. it is in the first group.
The largest size for kids are either 12's or 5's

fold a 3 by 5 index card 32 times and you get the size.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
The atomic radius of cobalt is about 135 pm (±5 pm).
if an element has 1 shell in its atom it is in period 1and so on... 2 shells=period 2 3 shells=period 3 4 shells=period 4 5 shells=period 5 6 shells=period 6 7 shells=period 7
The largest size that Spanx currently comes in for women is a size G which covers from a weight of 290 to 326 pounds and a height of 5 foot 2 inches to 6 foot 1 inches.
5 holds the least amount of compounded drug. 000 is the largest.
Assuming you're talking about the nucleus of an atom, the nucleus is very small relative to the atom's volume as a whole. However, it makes up nearly all of an atom's mass, because it contains all the protons and neutrons. So, relative to the total atom, the nucleus is very small and very dense.
As an ion, the maximum would be 2, 3, 4, 5, or 6 more than the number of protons in the atom, and the upper limit of atomic size is unknown. For the largest natural atom, uranium, the oxidation states are 3, 4, 5, and 6.
