What is atomic radius of an element?
The atomic radius is defined as one-half the distance between the nuclei of identical atoms that are bonded together. Figure 1. The atomic radius (r) of an atom can be defined as one half the distance (d) between two nuclei in a diatomic molecule. Atomic radii have been measured for elements.

What affects atomic radius?
The bigger the atomic number, the larger the atom’s radius. This is especially true as you move straight down a given column on the periodic table; the radius of each successive neighboring atom increases. The growing size is due to the increasing number of filled electron shells as you move down the periodic table.
What increases atomic radius?
In general, atomic radius decreases across a period and increases down a group. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
Does atomic radius increase with atomic mass?
The atomic number is the amount of protons present in the atom. Because of that, we can say that the atomic number represents the positive charge of the atom. But, the Atomic radius becomes larger as you move down the periodic table in a group or column because it increases the number of energy levels.
Does sodium or aluminum have a larger atomic radius?
Protons pull on electrons and make atoms smaller. Because of this, going from left to right in a periodic table makes the atoms smaller and smaller, since more and more protons are added. In this scenario, Aluminum is more to the right than Sodium, which means that it has more protons.
Which element has a larger atomic radius than aluminum?
Sodium has fewer electrons than aluminum and therefore a weaker inward pull on its electrons, which results in a bigger atomic radius. Which of the following elements has an atomic radius larger than that of aluminum? That’s answer (B) sodium.
Does Al or Na have a larger atomic radius?
Due to the addition of electrons in the same shell in Aluminum, the nuclear charge on Aluminium is more than that of Na and thus the atom tends to shrink a little in size. Hence, Al has a smaller atomic size than Na.
Does sodium have a larger atomic radius?
This means that its valence electron is in the second energy level. Sodium is in period 3 in group 1/IA, so its valence electron is in the third energy level, therefore it has a greater atomic radius than lithium. The size of an atom is usually known as its atomic radius.
Which has a larger atomic radius sodium or chlorine?
Thus sodium has larger size. As the no. of protons in Cl is more than Na, the nuclear force in the nucleus of Cl is more than that of Na which holds the valence electrons more tightly resulting in small atomic radius of Cl than that of Na.
Which has a larger atomic radius carbon or germanium?
Carbon also has a significantly smaller radius, higher electronegativity, and a higher ionization energy. Silicon and germanium are very much alike in all of their properties, as are tin and lead.
