An atom of deuterium is a hydrogen atom with an atomic mass of 2. Deuterium contains how many protons, neutrons, and electrons respectively?

1, 1, 1

Explanation:

Since Deuterium is an isotope of Hydrogen, which has 1 electron, it has one electron. And because the atomic mass is 2, and the atomic mass is the sum of the protons and neutrons, 1 proton + 1 neutron equals an atomic mass of 2. Hope this helped.

i'm pretty sure its b i might be wrong though!

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.
