Question

What is generally true of atoms with relatively large atomic radii?

Answer 1

Answer:

B. Large atoms tend to have a low ionization energy and a low electron affinity.

Explanation:

Atomic radii can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons. The atomic radius of a chemical element decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).

Generally, atoms with relatively large atomic radii tend to have a low ionization energy and a low electron affinity. Ionization energy can be defined as the minimum energy required to remove or detach an electron from a neutral atom in a gaseous state. Electron affinity can be defined as the ability of an atom of a chemical element to accept or accommodate an electron.
