Which physical properties do all stars have? check all that apply. they are made of gases? they shine very bright? they have a spherical shape? they contain iron in their cores? they make energy through fusion? @nattyames snap

All of the above

Explanation:

A star is a hot, giant, massive body that is located millions of miles away. These stars appears to be shiny because of its high temperature that glows producing light. They are comprised of gases such as hydrogen and helium, and they release a huge amount of energy when two hydrogen atoms undergoes fusion.

They generally look star shaped (circular type) from earth but they are somewhat spherical in shape due to their gravity that forces them to get bulge at its equator during its rotation around its own axis.

They have a core that contains iron in them and they progressively formed after the exhaustion of the hydrogen and helium fuel.

Hence, all the given options are correct.

The answer is A, C, E for E2020 users. I just took the unit test review.

Explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
