A covalent bond exists between a boron atom and an iodine atom. In this bond, the atoms share an electron pair to achieve a stable electronic configuration. Boron has 3 valence electrons, while iodine has 7, so they can share electrons to complete their outer electron shells.
Boron is an element, and there are certainly atoms of boron. Saying that "boron is an atom" is a slight misuse of terminology, though.
The formula for boron iodide is BI₃. It is a chemical compound composed of one boron atom and three iodine atoms.
The simplest formula for the compound formed between boron and fluorine would be BF3, which is boron trifluoride. Boron typically forms compounds by sharing 3 electrons with each fluorine atom, resulting in a molecule with a boron atom at the center and three fluorine atoms surrounding it.
The boron atom in BF3 has sp2 hybridization.
The Lewis structure of boric acid consists of a central boron atom bonded to three oxygen atoms. Each oxygen atom forms a single bond with the boron atom, and there is also a coordinate covalent bond between one of the oxygen atoms and the boron atom.

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.
One atom of potassium will react with one atom of iodine according to the balanced chemical equation for the reaction between potassium and iodine: 2K + I2 → 2KI.
A covalent bond exists between a carbon atom and a chlorine atom when they share electrons to achieve a stable electron configuration. Chlorine is more electronegative than carbon, so the shared electrons are pulled closer to the chlorine atom.
The atomic number of boron (5) indicates the number of protons in the nucleus of a boron atom. This means that a boron atom has 5 protons. Since atoms are electrically neutral, it also tells us that a boron atom has 5 electrons to balance the positive charge of the protons.
Boron, mostly.
A boron atom has three electrons in its second energy level.
A boron atom has fewer electrons than a lithium atom. Lithium has 3 electrons while boron has 5 electrons.
