Question

​

Answer 1

Answer:

1 : the quality or state of being senior : priority. 2 : a privileged status attained by length of continuous service (as in a company)

Explanation:

Metals are solids at room temperature with the exception of mercury and gallium, which are liquids at room temperature. Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). These have no metallic lustre, and do not reflect light.
