The element with the greatest number of valence electrons available for bonding is chlorine. Among all the choices, chlorine is the element that belongs to the higher group number, group 7.

The disc which contains spiral arms of the galaxy part would be used to study the birth starts in a spiral galaxy

- Bulge primarily contains old stars, gas and dust.
- The disc contains the spiral arms also, it is the flattened portion of the spiral arms where we could find most of the young stars, gas and dust. Some old stars are also found in this region
- Spiral arms are only found in spiral galaxies. It is the curved extension begins from the bulge. Here, also you could find young stars, dust and gas.
- Halo is the part where we could find clusters or individual old starts and also the dark matter. The dark matter we can't see but can estimate the gravitational force.
