Does sodium have the smallest atomic size?

Sodium, Aluminum, Sulfur, Chlorine Largest---------------------->Smallest

Hydrogen has the smallest atomic radius - 25 pm.

Chlorine will have the smallest atomic radius

Atomic size of sodium is 186

The smallest atom is hydrogen.

Hydrogen

The smallest atomic number and atomic weight for a lanthanide is lanthanum itself, element 57. The smallest atomic size is lutecium element 71; the lanthanides steadily decrease in atomic radius through the series, and the smallest is the last of them.

Hydrogen has the smallest atomic size of any element.

chlorine is the smallest in size. The order of atomic size is chlorine < sulphur < phosphorus < silicon.

across a period, the atomic size decreases as the effective nuclear charge increases.

Ar, using the table of atomic radii in wikipedia.

It is increasing down in the group. Li has the smallest.

Halogens have maximum effective nuclear charge. So the high number of protons in the nucleus attract electrons and thus the size of the atomic radii is the smallest.

chlorine. across a period the size decreases

Sodium has the largest atomic size in the third period.

Sodium is atomic / metallic.

Atomic radii become larger as you go from top to bottom of the periodic chart, but they get smaller as you go from left to right. Therefore, the elements with the smallest radii are in the upper right hand corner. Of S, Al, Na, and Ba, sulfur is the closest to the upper right corner and has the smallest radius of those elements.

the atomic number of sodium is 11.

The atomic mass of sodium is 22.99

The atomic weight of sodium is 22.989770.

Bromine, Copper, Calcium, Potassium Bromine- smallest, 4th period atomic #35 Copper- second smallest, 4th period, atomic # 29 Calcium- second largest, 4th period, atomic # 20 Potassium- largest, 4th period, atomic # 19

Looking at the atomic size,fluorine is the smallest of the halogen family.fluorine has an atomic number of 9 while iodine has its atomic mass to be 54.

Sodium is a meta element. Atomic mass of it is 23. Atomic number of it is 11.

Noble gases have the smallest atomic radius.

Hydrogen is a gas element. It had the smallest atomic number.

The atomic mass of sodium is 22.989768 a.m.u.

Sodium (Na) has the atomic number 11.

The Relative Atomic Mass of Sodium is 23.

The atomic number of sodium is 11.

Sodium (Na) has atomic number 11 and atomic mass of 22.99 g/mol

The atomic weight (not mass) of sodium is calculated after the determination of the atomic masses of each natural sodium isotopes by mass spectrometry.

Atomic number for sodium is 11. 2-8-1 is the electronic configuration of sodium.

A sodium atom has an atomic radius of about 2.23 angstroms.

Sodium is a meta element. Atomic mass of it is 23.

Sodium (Na) has an atomic mass of 22.989768.

'Na' is the atomic notation of sodium. Hope this helps :)

sodium= NA atomic number= 11

The atomic number of sodium is 11, and the symbol is Na.

Sodium (Na) is atomic number 11.

Sodium symbol is Na and its atomic number is 11.

Sodium = Na Atomic number = 11

Sodium is a metal element. Atomic number of it is 11.

The element that is considered to have the smallest atomic radius is helium. The other elements in the p-block of the periodic table also have small atomic radii, but helium is the smallest.

Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
