Question

use the image on the right to answer the next two questions.

1. identify the similarities and differences between the elements in group 1
2. how do the similarities identified change in a group moving from the top to the bottom of the column?

bonding
use the image on the right to help answer the following questions about bonds between elements.

1. what is the difference between a covalent bond and an ionic bond?
2. what occurs when a covalent bond forms and how are covalent bonds held together between two elements?
3. which two types of elements join in a covalent bond?
4. what occurs when an ionic bond forms and how are ionic bonds held together between two elements?
5. which two types of elements join in an ionic bond?
6. which type of elements give up electrons and which gain?

Explanation:

The problem involves questions about atomic structure (like group 1 elements' properties) and chemical bonding (covalent and ionic bonds). These topics fall under Chemistry, a subfield of Natural Science. The questions require knowledge of chemical concepts such as electron configuration, bond formation, and differences between bond types.

Answer:

The subfield is Chemistry (under Natural Science).
