Z=20; 1s22s22p63s23p6 express your answer as an ion

The ion formed is

Explanation:

An ion is formed when an atom looses or gains electron.

We are given:

Atomic number of element Z = 20

The electronic configuration of neutral atom =

The electronic configuration of the ion =

As, the given element is loosing 2 electrons. So, it will form a positive ion having charge of +2.

Hence, the ion formed is

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.
