Answer:

Here's what I get.

Explanation:

(a) #"K"#

#"K"# is in Group 1. It has one valence electron, so its Lewis structure is #"K·"#

(b) #"Mg"#

#"Mg"# is in Group 2. It has two valence electrons, so its Lewis structure is #"Mg:"#

(c) #"Sr"#

#"Sr"# is in Group 2. It has two valence electrons, so its Lewis structure is #"Sr:"#

(d) #"Br"#

#"Br"# is in Group 17. It has seven valence electrons, so its Lewis structure is
