What are group 1 metals called?
The Group 1 elements are called the alkali metals. They are placed in the vertical column on the left-hand side of the periodic table . All the Group 1 elements are very reactive .
What is a group 1 metal called?
The alkali metals
The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What family is cobalt?
transition metals
Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals“. It is one of only 3 ferromagnetic transition elements along with iron and nickel.
What are the 10 groups names on the periodic table?
Group
- Group 1: alkali metals, or lithium family.
- Group 2: alkaline earth metals, or beryllium family.
- Group 3: the scandium family.
- Group 4: the titanium family.

What is Group 8 element called?
noble gases
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
What is Group 13 called?
boron group element
boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What are Group 11 elements called?
coinage metals
Group 11 elements are inert and corrosion-resistant metals that are also known as coinage metals due to their use in coin minting. The valence electronic configuration of Group 11 elements are n – 1 d 9 ns 1 with oxidation state by the loss of single electron.
What is Group 14 in the periodic table?
Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level.
What metal is in group 1 Period 4?
Sodium is a soft, silvery metal that reacts very vigorously with water, and tarnishes easily in air. It is the fourth most abundant element in the Earth’s crust, which consists of 2.6% sodium by weight; seawater is about 1.5% sodium.

Is cobalt a iron?
Cobalt (Co) is a transition metal with an atomic weight of 58.93 and an atomic number of 27, right in between iron and nickel. Cobalt, however, is not as abundant as iron and only makes up of about 0.0020% of the Earth’s crust.
What are Group 2 metals called?
The Alkaline Earth Metals
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.
What is a group 1 and Group 2 metal?
Group 1: The Alkali Metals. Group 2: The Alkaline Earth Metals. Group 17: The Halogens. Group 18: The Noble Gases.
What is Group 2 known as?
They are called “alkaline” earth metals because they form “alkaline” solutions, hydroxides, when they react with water .
What are Group 7 metals called?
Group 7, numbered by IUPAC nomenclature, is a group of elements in the periodic table. They are manganese (Mn), technetium (Tc), rhenium (Re), and bohrium (Bh). All known elements of group 7 are transition metals.
What are Group 3 elements called?
Group III consists of two subgroups: group IIIb and group IIIa. Group IIIa consists of scandium, yttrium, and lanthanium, which is generally considered with the lanthanoids, and actinium, which is classified with the actinoids. Group IIIb, the main group, comprises boron, aluminium, gallium, indium, and thallium.
