Answer 1

Answer:

A,B are correct answer and C incorrect I think

Answer 2

Option (a)  All the statements A, B and C are correct

Explanation:

For Statement (A): Metals have low I.E so that valence electrons are easily removed from the atoms

• When an atom has higher ionization energy, it requires a lot of energy to remove an electron, and the atom is stable and has a lower reactivity.
• And Within each group of metals, reactivity increases as you go down the group. The valence electrons are less tightly bound and that valence electrons are easily removed from the metal atoms, because they are farther away from the nucleus of the atom.

For Statement (B): In metals, mobile electrons move randomly in different directions

• If the metal wire is left alone, the free electrons inside will move and collide with the atoms randomly.
• Free electrons in the wire from the strength of this electric field and accelerate towards the field (actually in the opposite direction, because the electrons are negatively charged).

For Statement (C): Na, K are soft metals

• The elements sodium and potassium are present in group 1 due to the presence of one valence electron.
• In addition, the metallic bond in the sodium is not strong, which makes cutting easier.

• It has a large atomic size, and for all these reasons metallic sodium and potassium are soft metals.

Hence, All the statements A, B, and C are correct
