A large atom decays and emits a particle. After the reaction is complete, the atom’s mass has changed substantially. What kind of particle has most likely been emitted?
alpha particle
beta particle
positron
photon

alpha particle

Explanation:

Alpha decay occurs when a nucleus is unstable because it has too many protons. The nucleus emits an alpha particle and energy. An alpha particle consists of two protons and two neutrons, which is actually a helium nucleus. Losing the protons and neutrons makes the nucleus more stable.

Hence, alpha emission means that the nucleus looses four mass units. Loosing four mass units leads to a substantial change in the mass of the nucleus. Hence the daughter nucleus is four mass units less than than the parent.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
