There's a trick to this. It's actually a really easy thing to remember so it wont take long for it to stick in your head.
Protons - Starts with P. Positive. Protons are the pro's they spread positive energy
Neutrons - similar name to its charge, Neutral. think of it like people who aren't positive or negatives. The Neutrals.
Electrons - Negative energy, Elect < Electricity. Electricity if you touch it is a bad thing, it reacts to your body negatively.
there ya go! :) be a proton.
They are positive
24 electrons, remember the atomic number of an element tells you how many protons it has. The number of protons = the number of electrons (if the atom isnt charged)
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
18 protons 18 electrons 22 neutrons
Roentgenium has 111 protons and electrons.
Parts of an atom: - protons - located in the nucleus - have a positive charge - neutrons - located in the nucleus - have a neutral or no charge - electrons - are in orbit around the nucleus - have a negative charge
Protons are positive, remember pro is +. Electrons are negative.
49 Remember an atom has the same number of electrons as protons.
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
24 electrons, remember the atomic number of an element tells you how many protons it has. The number of protons = the number of electrons (if the atom isnt charged)
Remember.. I f there are more electrons than protons in an ion the charge will be negative. Here there is a -4 charge because the electrons are higher than the protons, if it were the opposite the charge would be +4.
13 protons an easy way to remember what number of protons an element has is APES. A-atomic number, P-protons, E-electrons, S-same, so the atomic number and the numbers of protons and electrons are the same number
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
An ion is an atom with a charge. This means that the number of electrons does not match the number of protons, thus giving it a charge. If there are more electrons, it has a negative charge. If it has more protons, it has a positive charge. Remember though, an atom cannot lose or gain protons, only electrons.
15 electrons and 15 protons
Protons and electrons have mass and charge.
Protons do not contain electrons. Protons are positively charged, electrons negatively charged.
35 protons, 36 electrons
