Answer:
i think its b but i could be wrong
Explanation:
Answer:
Na is the element from the second period that has the largest atomic radius
Explanation:
The atomic radius is a chemist property from the periodic table. It is decreased when we move in a period from the periodic, so the element in the second period that has the largest radius is Na, and the shortest, the Ar
The atomic radius indicates the distance between the nucleus and the outermost valence layer. In the periods it decreases with increasing Atomic Number, to the right, due to the attraction that the nucleus exerts on the electrons of the outermost orbitals, thus decreasing the core-electron distance.
Answer: water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will ´´want´´ to have the smallest possible surface area. The shape that has the smallest possible area for a given area is a sphere.
