What is a subatomic particel? is a very small particle that is a building block for atoms
What is an Electron? is a subatomic particle that possesses a negative (-) electical charge
what is a Proton? is a subatomic particle that possesses a positive (+) electrical charge
what is a Neutron? is a subatomic particle that has no charge associated with it; taht is it is neutral
How are the subatomic particles within an atom arranged all protons and all neutrons present are found at the center of an atom in a very tiney volume called the nucleus, however Electrons are on the outer edge in the extranuclear
what is the nucleus? is the small sense positively charged center of an atom
what is a nucleon? it is any subatomic particle found in the nucleus of an atom
the number of protons in an atom = what Numer of electrons
what is the atomic number? is the number of protons in the nucleus of an atom, (atomic number = number of protons = number of electrons)
what is the atomic number of B (Boron), and how many protons, and electrons are present now lets remember atomic# = #of protons, also the atomic# is given at the top of each element of the periodic table so the atomic number, #protons, and #electrons for B, is 5
