you can find electrons by subtract the atomic number and atomic mass.
there are 5 electrons in boron
Valence electrons
Valence electrons are on the external shell.
an atom
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.
To find the valence electrons in a Bohr model, first identify the element's atomic number, which indicates the total number of electrons. In the Bohr model, electrons are arranged in specific energy levels or shells around the nucleus. The outermost shell corresponds to the valence electrons; count the electrons in this shell to determine the number of valence electrons. For example, if the outer shell has 5 electrons, the element has 5 valence electrons.
electron=atomic number
No
is a compound
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.
