Group 6, numbered by IUPAC style, is a group of elements in the periodic table. Its members are chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg)….Group 6 element.
| Z | Element | No. of electrons/shell |
|---|---|---|
| 74 | tungsten | 2, 8, 18, 32, 12, 2 |
| 106 | seaborgium | 2, 8, 18, 32, 32, 12, 2 |
Which elements are found in Period 6?
The period 6 transition metals are lanthanum (La), hafnium (Hf), tantalum (Ta), tungsten (W), rhenium (Re), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), and mercury (Hg).
What period is alkali metals?
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
Which 6th period element is a metal?
A period 6 element is an element in the sixth period (row) of the periodic table. It contains 32 elements, beginning at Caesium and ending with Radon. The Lanthanides are part of this period….Atomic characteristics.

Where are the alkali metals on the periodic table?
They occupy the first column of the periodic table. Alkali elements are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Cesium (Cs) and Francium (Fr) occupying successive periods from first to seven. Francium is a radioactive element with very low half-life.
What element has one electron and behaves like an alkali metal?
Hydrogen, like the alkali metals , has one valence electron and reacts easily with the halogens, but the similarities end there because of the small size of a bare proton H+ compared to the alkali metal cations.
Which is the most reactive alkali metal in the world?
Lithium melts at 180.5 °C (356.9 °F); cesium melts at just 28.4 °C (83.1 °F). These elements are also excellent conductors of heat and electricity. The alkali metals are very reactive and so are usually found in compounds with other elements, such as salt (sodium chloride, NaCl) and potassium chloride (KCl). What is the most common alkali metal?
Who was the discoverer of the alkali metal?
