Answer:
Explanation:
Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.
As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.
If we look at the halogens group (17), we see they follow this order from top to bottom:
F - Fluorine
Cl - Chlorine
Br - Bromine
I - Iodine
Since it increases down the group, iodine must have the largest atomic radius.
The answer to this question is D.
Explanation:
An apple pie is a mixture whereas lead iodide is a compound. To processes leading to the formation of a mixture and a compound are completely different.
- A compound is a substance composed of two or more kinds of atoms that are joined together to form a definite matter.
- The properties of the compound formed differs from that of the constituent atoms.
- A mixture on the other hand is made up of indefinite compositions.
- In the case of the apple pie, the parts are not homogeneous in nature.
To produce lead iodide, chemical reactions must take place between atoms.
In the case of the pie, chemical and physical changes can take place.

Answer:
Hey there
Explanation:
The process where organisms better adapted to their environment tend to survive and produce more offspring is called natural selection. It is one of the points of Darwinism by Charles Darwin.
