you can find electrons by subtract the atomic number and atomic mass.
there are 5 electrons in boron
Valence electrons
an atom
Valence electrons are on the external shell.
the number of valence electrons is the number group on the table its on
You can find this information from the periodic table.
Electrons are found outside the nucleus of the atom and they have negative charge.
electron=atomic number
is a compound
No
The baisc consept of an atom is a nucleus of protons and neutorons with electrons orbitting around it
The number of electrons in an atom is equal to its atomic number, which is the number of protons in its nucleus. This is because atoms are electrically neutral, so they have an equal number of protons and electrons. You can find the atomic number of an element on the periodic table.
