Answer:
fluorine (f) lies in group 17 and 2 period
Answer:
8.3
Explanation:
pH is the measure of the H+ or H30 (they r the same thing) ions in a solution. it is equal to -log[H+]. [H+]= Molar concentration of H+ ions.
Answer:
Boom
Explanation:
The bomb is big and it goes boom and it also creates nuclear fragments everywhere
The rate of the forward reaction equals the rate of the backward reaction. A dynamic equilibrium is a chemical equilibrium between a forward reaction and the reverse reaction where the rate of the reactions are equal.
Explanation:
Alpha particles are less penetrating than a beta or gamma particle. Alpha particles are doubly charged helium nuclei. It consists of two neutrons and two protons.
The penetration of any ray is given by the following relation :
T = e^-u * L
Where
T is the transmittance of any material
u is the coefficient of penetration
L is the length of penetration
The mass and charge of alpha particle is more as compared to beta and gamma particles. They can produce ions easily. So, they penetrate more when compared to beta and gamma rays.
