5 protons, 6 neutrons and 5 electrons
5. If it is more or less than 5 protons then it is not boron.
False: A compound whose molecules contain one boron atom and three fluorine atoms would be named "monoboron trifluoride" or simply "boron trifluoride".
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 boron atom in BF3 has sp2 hybridization.
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.

All atoms contain protons, neutrons and electrons.

Compounds that contain one boron atom and three fluorine atoms are known as boron trifluoride (BF₃). This molecule consists of a boron atom bonded to three fluorine atoms, forming a trigonal planar geometry. Boron trifluoride is a colorless gas at room temperature and is commonly used as a Lewis acid in organic chemistry and various industrial processes.

The boron atom in BF3 has sp2 hybridization.
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.
The compound is boron trifluoride, with the chemical formula BF3.
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.
