.-1, f-

give the correct chemical symbol for the ion formed when sodium loses one electron

Na+1

anion

an atom that has gained one or more electron e greater than p negative ion ex: Na+= cation cl- anion Mg+2=cation

cation

an atom that has lost one or more electrons p greater than e=positive ion more pos than neg ex: na+ k+

neutral atom

an atom with the same number of protons and electrons p=e ex=na, cl, mg,k

the chemical symbol s-2 represents a

anion formed as a result of a sulfur ion gaining 2 electrons

cation formed as a result of a iron atom losing 3 electrons

ion

charged atom

when a neutral atom gains an electron, it becomes a

negative anion
