Electromagnetic radiation<span>, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a </span>wave<span>, and has an oscillating electric field component and an oscillating magnetic field. These </span>waves<span> oscillate perpendicularly to and in phase with one another.</span>
If we dissolve salt in water they will reduce the intermolecular forces between water molecule and this will decrease the surface tension.
Surface tension is due to cohesive forces (the forces between molecules of same substance) hence as cohesive forces decreases the surface tension also decreases
Answer:
✅
Explanation:
DON'T USE DRUGS BECAUSE IT IS GOING DEATH
Answer:
Phosphorous has the smallest atomic size.
Explanation:
As we know these elements belong to same period means there valence shell is the same. So moving from left to right along the period the shell number remains constant but the number of protons and electrons increases. So, due to increase in number of protons the nuclear charge increases hence attracts the valence electrons more effectively resulting in the decrease of atomic size.
Elements and their atomic radius are as follow,

Baking soda is sodium bicarbonate in anhydrous form without any water of crystallisation and it is widely used as dry fire extinguisher because of its alkali nature.
