Which statement is true about the two stars labeled in this diagram? This is an elliptical galaxy and Star A is older than Star B. This is a spiral galaxy and Star A is older than Star B. This is a spiral galaxy and Star B is older than Star A. This is an elliptical galaxy and Star B is older than Star A.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

answerspecific gravity;

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.
