Alpha, beta and gamma radiation are all types of radiation that can be emitted from the nucleus of an atom. Apart from this they are different. Alpha radiation consists of a helium nucleus, beta radiation consists of an electron (or positron) and gamma radiation consists of very high energy electromagnetic radiation.
Answer: A
Explanation: Protons and neutrons form the nucleus of the atom, with electrons orbiting it.
Answer:
NH₃ (Option A)
Explanation:
Arrhenius theory explained that the acids are the ones that have H⁺, either H in its formula. Following this, the bases are the ones that have OH⁻ , either OH and its formula.
It can be used only with compounds with H, or OH.
So the ammonia is not a base, as Arrhenius theory.
It is known that ammonia behaves as a weak base, but it does not have hydroxide ions that can yield to water
