A period is the horizontal row of elements in the periodic table and they are numbered from one to seven. In the same period, atomic number increases from left to right. Elements in the same period have the same number of electron energy levels and they transition from a metal to noble gas.
Answer: Option (d) is the correct answer.
Explanation:
The amount of salt present or dissolved in water or water body is known as salinity.
When salinity increases then number of particles increases, therefore, density will increase. Also, number of ions will decrease thus, electrical conductivity will decrease.
On the other hand, increase in salinity will increase the amount of salt (NaCl) is the water.
Thus, we can conclude that out of the given options, the option all of the above is true.
