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 semimetal in group 5a.	yes / no
an alkali metal with a lower atomic number than sulfur.	yes / no
a transition element in period 6.	yes / no

Explanation:

Step1: Analyze Period 6 Group 7A

Elements in Period 6 Group 7A is Astatine (At). Its atomic number is 85 which is less than 92. So answer is Yes and symbol is At.

Step2: Analyze semimetal in Group 5A

Arsenic (As) and Antimony (Sb) in Group 5A are semimetals. As has atomic number 33 and Sb has atomic number 51, both less than 92. So answer is Yes. For example, we can choose As.

Step3: Analyze alkali - metal with lower atomic number than sulfur

Lithium (Li), Sodium (Na) are alkali - metals with atomic numbers 3 and 11 respectively, both less than sulfur's atomic number 16. So answer is Yes. For example, we can choose Na.

Step4: Analyze transition element in Period 6

There are many transition elements in Period 6 like Iron (Fe), Copper (Cu) etc. Their atomic numbers are less than 92. So answer is Yes. For example, we can choose Fe.

Answer:

Description	Does any element match?	If yes, give symbol
A semimetal in Group 5A	Yes	As
An alkali metal with a lower atomic number than sulfur	Yes	Na
A transition element in Period 6	Yes	Fe
