Which Has Smaller Atomic Radius Magnesium Or Phosphorus?

Magnesium has a larger atomic radius due to a smaller effective nuclear charge

Which element has a larger atomic radius than phosphorus?

This is due to the difference in the number of protons in the nucleus which affects the effective nuclear charge

Does magnesium or phosphorus have a larger atomic radius?

Magnesium has a larger atomic radius due to a smaller effective nuclear charge

Why does phosphorus have a smaller radius than magnesium?

Phosphorus has a larger atomic radius

Does magnesium have a larger atomic radius?

Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge

Why is the ionic radius of K+ smaller than CL?

In other words, K+ has bigger effective nuclear charge

What has the smallest atomic radius?

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

Which has a larger radius S or CL?

Sulphur(S) has the largest atomic radius

Which has a larger radius I mg or Ca II S or CL?

Calcium has a larger atomic radius than Magnesium. If you look on the period table you will notice Magnesium atomic number is 12, while Calcium is 20. Calcium(Ca) has 4 energy level while magnesium(Mg) has 3 Energy level.

Does sodium have a larger atomic radius than oxygen?

Therefore, even though a sodium ion and an oxygen ion have the same number of electron shells and the same number of electrons, a sodium ion is smaller because it has a greater number of protons. Or in other words, an oxygen ion is larger because it has fewer protons.

Why does calcium have a larger atomic radius than magnesium?

Because a calcium atom has more electrons (20) than a magnesium atom does (12), some of its electrons will be farther from the nucleus in a higher energy level. The magnesium atom’s electrons (12e-) occupy fewer energy levels than do the electrons of the calcium atom (20e-).

Which has a larger atomic radius magnesium or aluminum?

The atomic radius of elements decreases from left to right across a period.

Is K+ bigger than Br?

Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius

What is bigger K+ or Ar?

K is larger than K+ because K has an extra valence shell. K+ is larger than Ar.

Which has larger size BR or BR?

Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius
