Ba has a larger atomic radius than Mg because Ba has more energy levels and electrons than Mg, leading to increased electron-electron repulsion which pushes the outer electrons further apart. This results in a larger atomic radius for Ba compared to Mg.
Barium (Ba) is larger than Beryllium (Be) because as you move down a group on the periodic table, the atomic size increases. Barium is in a lower group than Beryllium and therefore has a larger atomic size.
Neither..they both have approximately the same weight as electrons are virtually weightless.bt the ba2 plus wud have to combine with another element for charge stability and the compound it forms shud be heavier than ba.
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.
Its Ba, Cl-, for the first 2, not sure on the last one, its confuseing if i had to guess i'd pick Cl-
Atomic number = number of protons Atomic mass number = number of protons + number of neutrons Relative mass number = the weighted average mass numbers of the naturally occurring isotopes as compared to C-12 If you delete the atomic number from the mass number you get the number of neutrons. The atomic number is the number of protons and electrons. (They are both the same number.)
Bismuth has an atomic radius of 156 picometers.
Barium (Ba) is larger than Beryllium (Be) because as you move down a group on the periodic table, the atomic size increases. Barium is in a lower group than Beryllium and therefore has a larger atomic size.
Both atoms have the same van der Waal's radius (2.00) Radii that are not available in either of these publications have RvdW 2.00 A. However, Caesium has a greater covalent radius (1.67) as compared to that of Radon (1.50) See the link for more info.
215 pico meters. This is from my Inorganic Chemistry book.

Barium (Ba), Radium (Ra) have atomic masses greater than strontium.
Atomic number = number of protons Atomic mass number = number of protons + number of neutrons Relative mass number = the weighted average mass numbers of the naturally occurring isotopes as compared to C-12 If you delete the atomic number from the mass number you get the number of neutrons. The atomic number is the number of protons and electrons. (They are both the same number.)
Mg (Magnesium) is lighter than Ba (Barium) on the periodic table. Magnesium has an atomic number of 12 and an atomic weight of 24.305 amu, while Barium has an atomic number of 56 and an atomic weight of 137.327 amu.
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.
