True or False? If false, write the correct term that's in UPPERCASE.
According to present atomic theory, the location of an ELECTRON in an atom is best represented by a probability cloud.
The mass of an ELECTRON is about equal to the mass of a proton.
Two isotopes of carbon are carbon-12 and carbon-14. These isotopes differ from one another by two ELECTRONS.
NONMETALS are poor conductors of heat and electricitiy.
Seven electrons in the outermost energy level is a characteristic of a METAL.

true
false -- neutron
false -- again neutrons
true (broad statement but I'm assuming we're not talking about electrically conductive polymers or great semiconductors -- depends on the instructor. A safer answer might be false, INSULATORS are poor conductors of heat and electricity.)
true - transition metal

true
the charge is opposite but not sure of the mass, but usually for every proton there is one electron...so maybe so. but i was under the impression that electrons had very little mass as compared to nucleons PROBABLY FALSE...NEUTRON
false NEUTRONS
true , conductors have 5 or more electrons in the valence shell ( outer shell ) insulators have 3 or less.... a semiconductor has exactly 4 electrons in the valience shell
true...see directly above

Momentum = mass x speed through regulation of conservation of momentum the sum of the momentums in the past = sum of the momentums after. it fairly is an occasion of an inelastic collision through fact on the tip the two bodies stick together so the momentum after of the two bodies is the same. yet in the past the bus has a lots greater advantageous momentum than the computer virus and its momentum is replaced little or no while the computer virus is now travelling very, very promptly which means it has so lots greater momentum than in the past. this suggests the momentum of the bus variations decrease than the momentum of the computer virus. i think of so any way...
