chlorine
magnesium (Mg)
From the given elements, Mg has the largest atomic radius, hence the size.
Beryllium (Be) is the least reactive among magnesium (Mg), lithium (Li), and beryllium (Be). Beryllium forms a protective oxide layer that prevents further reactions with air, whereas magnesium and lithium react more readily with oxygen and moisture in the air.
In one formula unit of MgCl2, there is one atom of magnesium (Mg) and two atoms of chlorine (Cl).
Sodium (Na) and Magnesium (Mg) are two elements in the same period (period 3).
magnesium (Mg)
From greatest to least tendency to accept an electron, they are F, O, C, Li, and Be.
Representative elements belong to s and p block. The elements are Sodium (Na), Magnesium (Mg) and chlorine (Cl)
Fluorine has the most electronegative element, Cl and Br
Representative elements belong to s and p block. The elements are Sodium (Na), Magnesium (Mg) and Chlorine (Cl).
These are elements having the valence two: Ba, Ca, Zn, Fe, Mg etc.
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
Magnesium chloride (MgCl2) has three elements: magnesium (Mg) and two chlorine (Cl) atoms.
Magnesium (Mg) and chlorine (Cl) are the elements present in magnesium chloride (MgCl2). MgCl2 is an ionic compound consisting of one magnesium ion (Mg2+) and two chloride ions (Cl-).
C and N, N and H, Cl and Cl, Xe and Xe can form covalent bonds. Mg and Cl, Li and Cl, Cu and Cl, Fe and Cl can form ionic bonds due to the large difference in electronegativity. K and Cl would form an ionic bond as well.
From the given elements, Mg has the largest atomic radius, hence the size.
MgCl2 contains the elements magnesium and chlorine.
