Protons It's a partical with a positive electrical charge
Malleable (of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking.
Density Amount of mass in a certain volume.
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.
Metalloides an element (e.g., germanium or silicon) 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.
Metals a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g., iron, gold, silver, copper, and aluminum, and alloys such as brass and steel).
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 A chemical symbol is a notation of one or two letters representing a chemical element.
Ductile (of a metal) able to be drawn out into a thin wire.
Corrosive tending to cause corrosion.
Atomic Mas the mass of an atom of a chemical element expressed in atomic mass units
Non – Metals an element or substance that is not a metal.
