What would change in the following picture to represent an isotope of the element chlorine? A.

Element - chlorine becomes argon after turning into an isotope

B.

Atomic Number - the number of protons increases which makes 17 become 18

C.

State of Matter - chlorine would become a liquid after turning into an isotope

D.

Atomic Mass - adding neutrons to protons increases the atomic mass

what's the rest of the question

answer increasing the intensity, duration,and frequency of exercise progressively;

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
