Examine the trend in atomic radius from top to bottom down a group by clicking on all the elements in the 1st group

As we go down in a group the atomic radius increases. Since the atomic number of the element increases. The number of protons will increase but, at the same time the number of electrons increases, so the distance from the last electron level (orbital) to the nucleus will be larger.

right

explanation:

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.
