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.
A boron atom has 5 electrons.
A boron atom has three electrons in its second energy level.
Trigonal planar
a boron atom has 5 protons and 6 neutrons inside the nucleus. the atom also has 5 electrons orbiting in the outer shells.
Each boron atom contains 5 protons in its nucleus.
Boron, mostly.
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.
Each boron atom has 5 electrons.
A boron atom has 5 electrons.
5 protons in one atom of boron. look at the periodic table.
Boron has more protons. It has 5, lithium has 3.
A boron atom has three electrons in its second energy level.
Trigonal planar
BF3 - Boron trifluoride
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.
There are exactly three electron pairs attached to the Boron atom, each one of them bonded to a chlorine atom as well.
