Question

The missing components in the table to the right are indicated with orange letters. Use the periodic table in the tools bar to fill in the corresponding values.

A
B
C
D

Answer 1

I don't have the table or the orange-letter positions. Could you either

- upload a photo/screenshot of the table (or paste the table text), or
- type what each letter (A, B, C, D) is asking for (e.g. "A = element at period 3, group 2" or "B = atomic number of sulfur"),

and I'll fill in the values.

If you want to find them yourself using the periodic table tool, here are quick steps for the common types of values:

- To find an element name or symbol from a position (group & period): find the intersection of that column (group) and row (period). The box gives the element symbol and name; the top number is the atomic number.
- To find atomic number: it is the integer in the element box (number of protons).
- To find atomic mass: use the number usually under the symbol (rounded atomic mass in amu).
- To find valence electrons: for main-group elements, equals the group number (for groups 1–2 and 13–18 use the last digit).
- To find oxidation states/electron configuration: click the element box in the tool for details.

Send the image or tell me what each letter refers to and I’ll fill A–D.
