Answer:

Two elements in same group having similar properties.

Explanation:

The elements shows similar properties if they have same number of valance electrons.

As we move left to right in periodic table the number of valance electrons increases in case of every element

When we move top to down in the group of periodic table the number of valance electrons remain same. So the elements in same group shows similar properties.

For example:

Fluorine and chlorine are present in same group, both have same valance electrons so they shows similar properties.

Electronic configuration of fluorine.

F₉ = [He] 2s² 2p⁵

Electronic configuration of chlorine.

Cl₁₇ = [Ne] 3s² 3p⁵

Both have same number of valance electrons that's why showing similar physical and chemical properties.

student plans to isolate chlorophyll, mix it in a solution of carbon dioxide and water, and then shine light on the mixture. Do
Inga [223]

Answer:

No

Explanation:

<u>In order for glucose to be produced inside the mixture, photosynthesis has to take place</u>. The photosynthetic process requires a series of steps within an organelle called the <u>chloroplast</u>. The chloroplast contains the chlorophyll and other enzymes that are necessary for photosynthesis.

<em>Once the chlorophyll is isolated, it becomes separated from the enzymes necessary for the completion of photosynthesis, and the process is truncated. </em>When light is shined on the mixture, the majority would instead be lost as heat while some cause the chlorophyll molecules to glow.
