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.

Does magnesium have a greater first ionization energy than strontium?
About twice as large, which is not that much at the first ionization level. Still, Magnesium has a slightly larger, one proton nucleus and one more electron in that valence level to add to the energy needed to pill the first electron out of it's orbital. Electron shielding may have something to do with this also as the other valance electron of this 2+ element may shield the pulled electron.
Where is the lowest electronegativity barium calcium magnesium or strontium?
Both are ions and we should consider the ionic radius, not the atomic radius. Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+). Both ions have the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.
Why are the properties of magnesium oxide different than the individual properties of magnesium and oxygen?
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.
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.
How can you determine the atomic weight of magnesium?
Look at periodic table posted in related links (no links are allowed in the answer) Find magnesium. There are two numbers (12 & 24.305). The larger one (24.305) is the atomic mass (average number of protons and neutrons). The smaller one (12) is the atomic number (number of protons). Atomic masses of chemical elements are determined now by mass spectrometry.
Which element in each pair has atoms with a larger atomic radius strontium or magnesium?
Strontium
Which element will have a larger atomic radius magnesium or cesium?
Caesium atom has a larger atomic radius.
What element has a larger atomic radius Magnesium or Bromide?
Bromide.

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.
Which element has a larger radius magnesium or sulfur?
What has a larger radii, a sulfur atom or sulfied ion and why
Which element has a larger ionic radius than calcium?
(Chlorine, Fluorine, anything that gains an electron when it ionizes) For example: when F becomes F−, it gains one electron but has the same number of protons, meaning the attraction of the protons to the electrons is weaker, creating a larger radius.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
a larger nuclear charge
Which element has a larger atomic radius carbon or germanium?
geranium

Which element has a larger atomic radius silicon or lead?
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
Which element has a larger atomic number than silver (Ag)?
