(im looking on the periodic table)

The atomic number (the big number in the middle or on top of the square) represents the number of protons in the atom, but since an atom is by definition neutral, the number of electrons is the same. For an ion, you would take the atomic number and subtract the charge, so for instance, carbon (atomic # 12) with a +1 charge would have 11 electrons.

The number of electrons are equal to the number of protons they have to cancel out eachothers charge to find the number of protons you use the number usualy in the top right mabe left called the atomic number example hydrogen would have 1 proton and one electron just be careful if you are working with isotopes or ions as that will change the electron count but leave the protons alone but if you arent into that in your science class yet then just do what i said above
good luck on ur science homework if that is what this is for : )

Look at the number at the top of the block for that element, that number corresponds to the number of protons in the nucleus of atoms of that element. The nuber of electrons will normally equal the nuber of protons unless the atom is an ion.

the atomic # is at the bottom of the periodic table usually (the atomic #'s go in order, for example hydrogen is #1)
The atomic # symbolises the # of protons in the element (there are always the same # of protons as there are electrons in the element)
(so... hydrogen is atomic #1, has 1 proton, and 1 electron)

You look at the atomic number of the element. For H it will be 1.

Drop the element on the kitchen floor and count the electrons as you pick them up (and don't forget those 2 in the cats dinner)
