The atomic number of an element is the total number of which subatomic particles in the nucleus?

The atomic number of an element is determined by the number of protons present in an atom.

Explanation:

There are 3 sub-atomic particles in an atom. They are: electrons, protons and neutrons.

Atomic number is defined as the number of protons that are present in a neutral atom. It is represented as Z.

Z = Atomic number = Number of protons

Hence, the atomic number of an element is determined by the number of protons present in an atom.

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.
