Question

read each description in the first column of the table below. if any chemical element with atomic number of 92 or less matches the description, check yes and enter the chemical symbol of an element that matches. otherwise check no in the second column.

description	does any element with z ≤ 92 match the description?	if you checked yes, give the symbol of an element with z ≤ 92 that matches.
a metalloid in group 5a.	yes no
an alkaline earth metal with a lower atomic number than indium.	yes no
a transition element in period 5.	yes no

Explanation:

Step1: Locate element in Period 6 and Group 1A

In the periodic - table, the element in Period 6 and Group 1A is Cs (cesium).

Step2: Identify metalloid in Group 5A

The metalloid in Group 5A is As (arsenic).

Step3: Find alkaline - earth metal with lower atomic number than indium

Alkaline - earth metals are in Group 2A. Indium (In) has atomic number 49. Magnesium (Mg) with atomic number 12 is an alkaline - earth metal with lower atomic number than indium.

Step4: Select transition element in Period 5

There are many transition elements in Period 5. For example, Ag (silver) is a transition element in Period 5.

Answer:

1. Yes, Cs
2. Yes, As
3. Yes, Mg
4. Yes, Ag
