- A vertical row of elements

Answer 1

Answer:

(☞ﾟ∀ﾟ)☞(☞ ಠ_ಠ)☞

A vertical row of elements.

Explanation:-

Group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts.

Answer 2

$\huge{\dag} \: {\underline{\boxed{\sf{\pink{ Answer }}}}}$

• Group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts.

• 9 Element Families
• Alkali Metals: Group 1 (IA) - 1 valence electron. Alkaline Earth Metals: Group 2 (IIA) - 2 valence electrons. Transition Metals: Groups 3-12 - d and f block metals have 2 valence electrons. Boron Group or Earth Metals: Group 13 (IIIA) - 3 valence electrons

• The elements that are generally considered other nonmetals include hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, and selenium. Nitrogen and phosphorus are included in the subgroup pnictogens. Oxygen, sulfur, and selenium are included in the subgroup chalcogens.

• In the Modern Periodic Table, there are 18 vertical columns known as Groups and 7 horizontal rows known as Periods.
