Question

1. go to the interactive periodic table and indicate the type of elements that are in neon green color.

a. metals \t\t\tb. non metals \t\t\tc. metalloids
list the element symbols for the elements that are designated with neon green below.

1. go to the interactive periodic table and indicate the number of elements that belong to the halogen family

list the member elements by their symbol.

11a. what is the name of group 2 on the periodic table?
11b. list three properties of group 2 elements.

Explanation:

Question 9

Neon green in many interactive periodic tables designates non - metals (option b). Non - metals are elements that lack the typical properties of metals, like luster, good conductivity, and malleability. Elements such as H, He, C, N, O, F, Ne, P, S, Cl, Ar, Se, Br, Kr, I, Xe, At, Rn are non - metals (the ones in neon green would be a subset of these, depending on the table's color - coding).

The Halogen family (Group 17) has 6 elements. The elements are Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), Astatine (At), and Tennessine (Ts).

Group 2 on the periodic table is called the Alkaline Earth Metals. This group consists of elements like Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).

Answer:

Type of elements: b. Non metals
Element symbols (example, depending on table): H, He, C, N, O, F, Ne (exact symbols depend on the specific interactive table's neon - green - coded elements)
