Question

unit test 1c - periodic table and periodic trends adv
refer to the periodic table below to answer the following questions
note: the answer choices are enclosed in parenthesis
element that has the same number of valence electrons as b: (m, k, r, or h)
is an alkaline earth metal (g, e, a, or d)
has 6 valence electrons. (h, p, b, or m)
is a member of the most reactive group of non - metals (g, x, z, or p)

Explanation:

Step1: Recall valence - electron rule

Elements in the same group have the same number of valence electrons. B and M are in the same group, so they have the same number of valence electrons.

Step2: Recall alkaline - earth metal location

Alkaline - earth metals are in group 2 of the periodic table. A is in group 2.

Step3: Recall number of valence electrons for group 16

Elements in group 16 have 6 valence electrons. H is in group 16.

Step4: Recall most reactive non - metals

Halogens are the most reactive group of non - metals. P is a halogen.

Answer:

Element that has the same number of valence electrons as B: M
Is an Alkaline Earth Metal: A
Has 6 valence electrons: H
Is a member of the most reactive group of non - metals: P
