What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.
Which element in each pair has atoms with a larger atomic radius selenium oxygen?
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
How do you tell the size of an elements atomic radius?
The atomic radius of chemical elements is expressed in picometers (pm).
Why is Mg smaller than Cl?
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.
Which element has a smaller atomic radius bromine or gold?
The atomic radius of bromine is lower.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.

Which element in each pair has atoms with a larger atomic radius strontium or magnesium?
Strontium
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
The atomic radius of potassium is smaller than the atomic radius of?
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.
How do you tell the size of an elements atomic radius?
The atomic radius of chemical elements is expressed in picometers (pm).
Element M reacts with chlorine to for a compound MCl2 Element M is more reactive than magnesium and has a smaller radius than barium the element is?
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.
Why is Mg smaller than Cl?
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.
What element has the smallest atomic radius?
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
Which element has a smaller atomic radius bromine or gold?
The atomic radius of bromine is lower.
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
