by subtracting 8 from the group number. this was answer by a Sone.
Carbon, Silicon (a metalloid), Germanium (a metalloid),
Carbon is in the same group as lead.
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
Fluorine is classified as a nonmetal. It is a highly reactive, gaseous element that belongs to the halogen group in the periodic table.
The halogens.
How to determine these ions:metal cations: find the positive charge, and make sure it is qual to the group numbernonmetal anions: subtract 8 from the group numbertransition metals cations: the number of electrons lost
Oxygen usually has a -2 charge as it is a group VI nonmetal. Most of the elements in group VI have -2 charges when they form ions.
price fixing
The ionic charge of a group 1A, 2A, or 3A ion is determined by the number of electrons lost or gained to achieve a full valence shell. Group 1A ions lose 1 electron to attain a +1 charge, group 2A ions lose 2 electrons for a +2 charge, and group 3A ions lose 3 electrons for a +3 charge.
Sulfate is a negative ion composed of the nonmetals sulfur and oxygen bus is itself not a metal or a nonmetal. The sulfate ion does not exist as a substance on its own. Its charge must be balanced by a positive ion the identity of that ion is variable.
Sulfur is classified as a nonmetal. It is a nonmetallic element found in group 16 of the periodic table.
No. Chlorine is a main group element, but is a nonmetal in the halogen family (group 17).
Carbon, Silicon (a metalloid), Germanium (a metalloid),
Carbon is in the same group as lead.
group 17, halogens
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
Helium is a nonmetal. It has properties that classify it as a noble gas, which is a group of nonmetals that are generally unreactive.
