What is the group number of a nonmetal?
Non-metals are the elements in groups 14-16 of the periodic table.
Which groups are metals and nonmetals?
Metals, Nonmetals, and Semimetals. The heavy orange zigzag line running diagonally from the upper left to the lower right through groups 13–16 in Figure 2.5. 1 divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line).
Is Group 4 metals or nonmetals?
Group IV consists of two subgroups: group IVb, main group, and group IVa. Group IVa consists of titanium, zirconium, and hafnium which are generally classified as transition metals. The main group consists of carbonium, silicium, germanium, tin, and lead.
What group numbers are metals?
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges….Metals, Metalloids, and Nonmetals.

Is Na a metal or nonmetal?
sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal.
What groups are nonmetals in periodic table?
Nonmetals: Everything else to the upper right of the staircase — plus hydrogen (H), stranded way back in Group 1 — is a nonmetal. These include carbon (C), nitrogen (N), phosphorus (P), oxygen (O), sulfur (S) and selenium (Se).
What are the 3 groups of metals?
There are three main types of metals ferrous metals, non ferrous metals and alloys. Ferrous metals are metals that consist mostly of iron and small amounts of other elements. Ferrous metals are prone to rusting if exposed to moisture. Ferrous metals can also be picked up by a magnet.
Are group 5 elements metals or nonmetals?
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
What are Group 7 elements called?
the halogens
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
How do you classify elements into metals or nonmetals?
Explanation: i) Elements which contain 1 to 3 electrons in their outermost shell are metals. Elements containing 4 to 7 electrons in their valence shell are non-metals. Hence A and C are metals whereas, B, D and E are non-metals.
Is Group 13 metal or nonmetal?
metalloid
Group 13 is called the boron group, and boron is the only metalloid in this group. The other group 13 elements are metals. Group 14 is called the carbon group. This group contains two metalloids: silicon and germanium.
