5
Each boron atom contains 5 protons in its nucleus.
there are 16 nuetrons in phosphorus atom
5- the atomic number of boron is 5. Atomic number is the number of protons and this is the same as the number of electrons in the neutral atom.
False: A compound whose molecules contain one boron atom and three fluorine atoms would be named "monoboron trifluoride" or simply "boron trifluoride".
A boron atom has 5 electrons and three of them are located in the valence shell.
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.
mass number
The Mass Number.
Each boron atom contains 5 protons in its nucleus.
mass number = protons + nuetrons
Number of Neutrons = Mass number - Atomic Number
Isotope.
there are 16 nuetrons in phosphorus atom
there are 12 nuetrons in an atom of magnesium
5- the atomic number of boron is 5. Atomic number is the number of protons and this is the same as the number of electrons in the neutral atom.
The most common isotope is 20
mass number = protons + nuetrons
