Except for ions, the number of electrons in an atom are equal to the number of protons. The atomic number will tell you the number of protons, and consequently the number of electrons in an electrically neutral atom.
In the case of an ion, adjust the number by the indicated charge; for example Na+1 will have 11 (the atomic number of Na) - 1 (since electrons have a negative charge, you subtract the charge) = 10 electrons.
A nitrogen atom has seven electrons.
A germanium atom has 32 electrons.
An atom of selenium has 34 electrons.
A copper atom has 29 electrons.
There are 17 electrons i a neutral atom of chlorine.
Generally how many protons it has, therefore what type of atom it is (i.e. carbon, hydrogen etc.)
phosphorus have 15 electron because you know the atomic number to know electron
Finding the number of electrons in an atom is easy. You just have to know the atomic number of the element. The atomic number for Potassium is 19. That means Potassium has 19 electrons.
A nitrogen atom has seven electrons.
Helium atom has 2 electrons.
A Mercury atom has 80 electrons.
The number of electrons depends on what type of atom it is.
A germanium atom has 32 electrons.
you see how many electrons and protons it has and add them together
The number of unpaired electrons in valence shell or numbers of electrons less then 8 in outermost shell of an atom give information about covalent bonds my be formed by an atom.
An atom of selenium has 34 electrons.
The neutral atom of potassium has 19 electrons.
