Best answer: What are rows 6 and 7 on the periodic table?

What is row 6 on the periodic table called?

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). These are all transition metals and chromium, molybdenum and tungsten are refractory metals.

Group 6 element.

Hydrogen Potassium

How many elements does Period 6 have?

The sixth period contains 32 elements, tied for the most with period 7, beginning with caesium and ending with radon.

Which is more metallic sodium or lithium?

Explanation: Metallic character means the reactivity of a metal. … Also, when we move down the group there is decrease in metallic character of elements. Since, Li, Na, and K all belong to the same group therefore, Li has highest metallic character.

What are horizontal rows on the periodic table called?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

What is the difference between rows and columns in the periodic table?

Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

Is silicon a metal?

But unlike carbon, silicon a metalloid — in fact, it’s the most common metalloid on earth. “Metalloid” is a term applied to elements that are better conductors of electron flow — electricity — than nonmetals, but not as good as metals.

Why are the first 3 rows of the periodic table arranged the way they are?

The SQA Data Booklet gives more information. The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. … This is because they have the same number of outer electrons and the same valency.

Why are there 32 elements in 6th period?

According to Pauli’s exclusion principle, each orbital can accommodate a maximum of only 2 electrons. Thus, 16 orbitals can accommodate a maximum 32 electrons. Hence, we justified that the sixth period of the periodic table should have 32 elements.
