The positive ionic radius is smaller than the neutral atomic radius
Magnesium is an element with a +2 charge when it forms ionic compounds, not a negative one.
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.
Magnesium and iodine react to form the ionic compound magnesium iodide - MgI2.
Examples are: Be, Al, Ti, V, Mn, Co, Ni etc.
ionic charge and ionic radius; the smaller the ionic radius the greater the lattice energy
The element with the smallest negative ionic radius is fluorine (F). It has a small ionic radius due to the high effective nuclear charge, which attracts the electrons closer to the nucleus in the ionic form.
Potassium has a larger ionic radius than sulfur.
The ionic radius of magnesium (Mg) affects its chemical properties. As the ionic radius decreases, the attraction between the nucleus and electrons increases, leading to higher reactivity and stronger bonding with other elements. This can influence properties such as solubility, melting point, and chemical reactivity of magnesium compounds.
The list from smallest to largest ionic radius would be: Be2+, Mg2+, Ba2+, Ra2+. Beryllium and magnesium ions have smaller ionic radii due to their higher charge and stronger attractive forces compared to barium and radium ions.
Ionic Charge and Ionic Radius - the smaller the radius the greater the lattice energy
Ionic Charge and Ionic Radius - the smaller the radius the greater the lattice energy
An element that has a larger ionic radius than calcium is strontium. Strontium is located below calcium in the same group of the periodic table, which means it has an extra energy level and therefore a larger ionic radius.
the positive ionic radius is smaller than the neutral atomic radius
Phosphorus has larger ionic radius than sulfur. There is more nuclear attraction in sulfur.
Magnesium is an s-block element and it forms only ionic bonds with other elements.
