Boron is an element, and there are certainly atoms of boron. Saying that "boron is an atom" is a slight misuse of terminology, though.
Each boron atom contains 5 protons in its nucleus.
Iodine
A boron atom has 5 electrons.
A boron atom has three electrons in its second energy level.
Covalent bond exists between a carbon atom and a chlorine atom.
This is not an atom of the element Boron (group 13, period 2), between Berillium and Carbon in the Periodic table. It is a non-existing negative ion of Boron.

Boron, mostly.
polar covalent
The symbol of a boron atom is "B", and the number of electrons in a neutral atom is the same as the number of protons, which equals the atomic number of boron: 5.
Iodine
An iodine atom has seven valence electrons.
Each boron atom has 5 electrons.
A boron atom has 5 electrons.
An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
