Answer:
all of these elements are classified as metals on the periodic table
Explanation:
some common physical properties they have is that they are all soilds (at room temperature), they are malleable (easily bent/shaped) and ductile, and they are good conductors of heat and electricity. they also have high melting points and have a metallic appearance.

Because its true our solar system is big
Answer:
As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off.
Answer:
Living things are carbon-based because carbon plays such a prominent role in the chemistry of living things. This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
