Bromide.
a larger nuclear charge
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
Hg
Induim because as you go across a group and down a period (or across a period and down a group, I forget which is correct) the atomic radius gets larger.
Potassium.
Caesium atom has a larger atomic radius.
Strontium
Strontium: At least within periodic table columns that do not include transition metals, an element with higher atomic number always has a larger atomic radius. This principle is generally correct also for columns that do include transition metals, but in an important exception, hafnium has almost the same atomic radius as zirconium, making the separation of these two metals very difficult by chemical means.
What has a larger radii, a sulfur atom or sulfied ion and why
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
a larger nuclear charge
geranium
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
Hg
Francium has the most larger atomic weight and also the largest atomic radius between the alkali metals.
Because of the interaction between each element's sub atomic particles. Magnesium has its specific properties because of the way it's electrons are arranged. Oxygen has different properties because it has a different electron arrangement. When combined, the resulting molecule is larger and has a different, more complex arrangement of sub atomic particles interacting with each other.
Magnesium isn't smaller than chlorine, it's larger. The atomic radius for magnesium is 145 pm and the atomic radius for chlorine is 79 pm. Both magnesium and chlorine are in the third period of the periodic table. The trend for atomic radius is that the elements generally get smaller as you move from left to right across the table in the same period.
