this is because the effect of the increased nucleus i roughly balanced by the greater screening effect produced by adding to the penultimate shell
The alkali metal with an atomic radius of 238 pm is potassium (K). Its large atomic radius is due to the added electron shells compared to other alkali metals in the same period.
Only the atomic radius is equivalent - 128 pm.
No, the atomic radius and atomic mass are not the same. The atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outer electron cloud. On the other hand, atomic mass is the mass of an atom, which is the sum of the protons and neutrons in the nucleus.
The empirical atomic radius of rubidium is 235 pm.The empirical atomic radius of caesium is 260 pm.The empirical atomic radius of francium is supposed to be approx. 260 pm.
Oh, what a delightful question! Strontium has a larger atomic radius than magnesium. You see, as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of more electron shells. So, in this case, strontium, being located below magnesium on the periodic table, has a larger atomic radius.

Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.

The atomic radius is the same thing as the Atomic Mass.
Not necessarily. The atomic radius of an element is determined by the size of the atom's electron cloud. While atoms of the same element would typically have the same atomic radius, atoms of different elements can vary in size due to differences in their electron configurations and the number of protons in their nuclei.
The atomic radius of manganese is about 127 picometers. In the periodic table, manganese has a smaller atomic radius compared to elements in the same period but larger than elements in the same group.

* Atomic Radius: 0.79Å * Atomic Volume: 14.4cm3/mol * Covalent Radius: 0.32Å * Ionic Radius: 0.012Å * Atomic Radius: 0.79Å * Atomic Volume: 14.4cm3/mol * Covalent Radius: 0.32Å * Ionic Radius: 0.012Å
Atomic radius is a measure of the size of an atom, typically defined as half the distance between the nuclei of two atoms of the same element that are bonded together. It represents the average distance from the nucleus to the outermost electron shell. Atomic radius generally decreases across a period on the periodic table and increases down a group.
