What will be the atomicity of:
a) The molecule which we consume during respiration and during photosynthesis it is released.
b) The red coloured element which we use in match boxes.
c) The pale blue gas which forms a layer that absorbs sun's UV radiation.
2, 4, 3 respectively
The elements are Oxygen, Phosphorus and Ozone respectively. So their atomicity is 2, 4, 3 respectively as the Oxygen molecule has 2 atoms each, Ozone molecule has 3 Oxygen atoms combined together and Phosphorus element has 4 Phosphorus atoms combined together.
