What information about elements can be collected from the periodic table?

A lot

Explanation:

- As you go down a group, the elements get larger in size

- All of the elements of the same group have the same # of valence electrons

- As you go to the right of a period, the # of electrons in the outermost shell increases

- The elements at the top right of the table have the highest electronegativity

- Groups 13 through 17 are nonmetals

- The last group contains noble gases

etc.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
