Among the elements Ca, Mg, P and Cl, the order of increasing atomic r...
Explanation:
Atomic Radii:
- Atomic radii are the distance from the nucleus of an atom to the outermost electron shell.
- It is a measure of the size of an atom.
Order of Increasing Atomic Radii:
1. Cl (Chlorine):
- Chlorine has the smallest atomic radius among the given elements.
- It has a high effective nuclear charge due to the presence of 17 protons in the nucleus, which attracts the electrons more strongly.
2. P (Phosphorus):
- Phosphorus has a slightly larger atomic radius compared to Chlorine.
- With 15 protons in the nucleus, the effective nuclear charge is lower than Chlorine, resulting in a larger atomic radius.
3. Mg (Magnesium):
- Magnesium has a larger atomic radius than Phosphorus.
- It has 12 protons in the nucleus, leading to a lower effective nuclear charge and a larger atomic radius.
4. Ca (Calcium):
- Calcium has the largest atomic radius among the given elements.
- With 20 protons in the nucleus, the effective nuclear charge is lower than the other elements, resulting in the largest atomic radius.
Therefore, the correct order of increasing atomic radii among the elements Ca, Mg, P, and Cl is:
Cl < p="" />< mg="" />< />
