Question:

$\text{Incorrect statement about metal is:}$

Options:

1. $\text{Metals can donate electrons.}$
2. $\text{Metals form ionic compounds.}$
3. $\text{Metals are more electronegative.}$ (Correct)
4. $\text{Metals have less ionization energy.}$

Solution:

$\text{HINT- The most right elements in periodic table are metals.}$\n\n$\text{Explanation:}$\n\n$\text{Properties of Metals :}$\n\n$\text{1. Metals can lose electrons easily.}$\n\n$\text{2. Metals cannot gain electrons easily.}$\n\n$\text{3. Metals generally form ionic compounds.}$\n\n$\text{4. Metals oxides are basic in nature.}$\n\n$\text{5. Metals have low ionization enthalpies.}$\n\n$\text{6. Metals have less negative electron gain enthalpies.}$\n\n$\text{7. Metals are less electronegative. They are rather electropositive elements.}$\n\n$\text{8. Metals have a high reducing power.}$
