Answer:
A
D
E
and maybe C I'm not sure on that one.
Explanation:
While staying in the same period, if we move from left to right across the period, the atomic radius decreases. The reason is, in a period the number of shells remain the same and the number of electrons and protons increase as we move across the period to the right. The increased electrons and protons attract each other with greater force and hence the atomic size decreases.
So the element on the left most will have the largest atomic radius. So the correct ans is Potassium. Potassium will have the largest atomic size among Potassium, Calcium and Scandium.
The answer would be B) Dunes. I hope you have a wonderful day :)
Answer: b.) they tend to lose electrons to gain stability
Explanation:
When a liquid is frozen, the atoms in the liquid slow their movement due to lack of energy so the substance becomes hard.
