Drag the tiles to the boxes to form correct pairs. Use the Hertzsprung-Russell diagram to determine which condition describes each star. Use the arrows to help locate the stars.

A) Betelgeuse
B) the Sun
C) Sirius B

The star can no longer support nuclear fusion because it has exhausted its supply of hydrogen:

The star’s hydrogen supply is running low, so it is fusing hydrogen from outside the core:

The star is experiencing nuclear fusion at its core:

the answer is

answeridentity;

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
