(+) +2
what is the charge on a flouride ion that has gained one electron?
.-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
the chemical symbol fe+3 represents
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
give the correct chemical symbol for the ion formed when oxygen gains 2 electrons
o-2
when a neutral atom loses an electron, it becomes
positive cation
