Question

Which statement explains why large atoms are more reactive than small atoms?

A.
Large atoms have valence electrons farther from the nucleus and lose them more readily.
B.
Large atoms have greater ionization energy, which they can utilize during a reaction.
C.
Large atoms have a greater number of electrons that they can lose during a reaction.
D.
Large atoms have more energy levels, so they have more energy to pass on in a reaction.

Answer 1

A. Large atoms have valence electrons farther from the nucleus and lose them more readily.

Step-by-step explanation:

For example, the valence electron of a small atom like Li is tightly held. Lithium gently fizzes on the surface as it reacts with the water to produce hydrogen.

In contrast, the valence electron of a large atom like Cs is so loosely held that cesium exlodes on contact with water.

Answer 2

A. Large atoms have valence electrons farther from the nucleus and lose them more readily, so they are more reactive than small atoms.

For example, the valence electron of a small atom like Li is tightly held. Lithium gently fizzes on the surface as it reacts with the water to produce hydrogen.

In contrast, the valence electron of a large atom like Cs is so loosely held that cesium exlodes on contact with water.
