Which of the following elements would lose an electron easily ?a)Mgb)Nac)Kd)CaCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

As we move down a group in the periodic table, the tendency to lose electron increases.
Also when we move from left to right in a period, the tendency to lose electrons decreases. Combining these two results, K will lose the electron most easily.

Answer

Bcoz it has valence of 1 electron.....

Answer

¶¶¶{# BECÃUSE # POTASSIUM (K) Come from period /4/ so it contain 4 shells, which means that the the last shell faces at least low nuclear force. Then it is easy to LOSE ELECTRONS from last shell.}¶¶¶

Answer

The sodium atom wants to lose an electron and the chlorine atom wants to gain an electron. When the two atoms come together the electron from the sodium atom jumps into the gap in the outer shell of the chlorine atom.

Answer

Potassium will loose electron easily..

..due to bigger size (size increases as we move from top to bottom in a group)n less ionisation potential n also bcz it is more electropositive n hence ionizes easily...

hope u got it:)

Answer

Potassium is most reactive metal from these.so it lose electron easily

Answer

Because potassium is the most reactive metal.So,it would lose an electron easily.

Answer

Explanation:
When an atom loses an electron, it forms a positively charged ion called a cation. The tendency of an element to lose an electron and form a cation is known as its electronegativity.

The electronegativity of an element depends on several factors, including the number of valence electrons it has and its atomic radius. Generally, elements with a smaller atomic radius and fewer valence electrons have a higher electronegativity, meaning they are more likely to lose an electron easily.

Comparison of the Elements:
Let's compare the electronegativity of the elements given in the options to determine which one is most likely to lose an electron easily:

a) Magnesium (Mg):
- Magnesium is located in Group 2 of the periodic table, meaning it has 2 valence electrons.
- Its atomic radius is larger than the elements in Group 1 but smaller than the elements in Group 3.
- Magnesium has a relatively low electronegativity, but it is not as likely to lose an electron easily as the elements in Group 1.

b) Sodium (Na):
- Sodium is located in Group 1 of the periodic table, meaning it has 1 valence electron.
- Its atomic radius is larger than both magnesium and potassium.
- Sodium has a lower electronegativity than magnesium, but it is still not as likely to lose an electron easily as the element in Group 1.

c) Potassium (K):
- Potassium is also located in Group 1 of the periodic table, meaning it has 1 valence electron.
- Its atomic radius is larger than both magnesium and sodium.
- Potassium has the lowest electronegativity among the options given, making it the most likely to lose an electron easily and form a cation.

d) Calcium (Ca):
- Calcium is located in Group 2 of the periodic table, meaning it has 2 valence electrons.
- Its atomic radius is larger than the elements in Group 1 but smaller than the elements in Group 3.
- Calcium has a higher electronegativity than magnesium but is not as likely to lose an electron easily as the elements in Group 1.

Therefore, the element most likely to lose an electron easily among the given options is potassium (K).
