Select the correct locations on the periodic table.

Explanation:
It is known that atoms that have same number of valence electrons will show similar chemical properties.
So, when we move from left to right across a period there occurs increase in number of valence electrons of each element. But when we move down a group then number of valence electrons remain the same.
Hence, elements of same group will show similar chemical properties.
Therefore, we can conclude that elements marked as 2 and 3 will have similar chemical properties.

The quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.
<h3>What is the speed of light?</h3>Speed of light is the rate of speed though the light travels. To find the speed of light in any medium, the following formula is used.
Here, (n) is the index of reaction and (c) is the speed of light in the vacuum. The speed of light in the vacuum is almost equal to the 3.0×10⁸ m/s.
Now the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water has to be find out.
The above formula can be written as,
Here, the product of index of refraction and speed of light is equal to the speed of light in vacuum. This will be true for water as well.
Thus, the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.
