There are two questions 1. what is the energy associated with electromagnetic radiation of 6.34 x 10^15 hertz

2. What is the frequency of one of the bands of the sodium emission spectrum that has a wavelength of 585 nanometers?

Yeah irbyoundo this you will get the a swer wuick

The chemical bubbles

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Idon't know hope someone you
