Question Answer
protons a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
malleable (of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking
atomic number the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
density amount of matter in a certain space
metalloids an element whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors.
electrons a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids
metal a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
luster a gentle sheen or soft glow, especially that of a partly reflective surface
neutrons a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
chemical symbol abbreviation for a cemical
ductile (of a metal) able to be drawn out into a thin wire.
corrosive property of meatsl rusting
atomic mass the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom
nonmetal group thats a poor conducted of heat and electricity also brittle
atom the smalles thing in the world // cant be seen// makes up everything
element a part or aspect of something abstract, especially one that is essential or characteristic.
melting making an solid into a liquid
evaporation the process of turning from liquid into vapor
condensation water that collects as droplets on a cold surface when humid air is in contact with it.
freezing turning a liquid back into a solid
sublimation a solid turning into a gas without becoming a liquid first
deposition a gas turning into a solid with out becoming a liquid frist
