True.
Plutonium is used for making nuclear bombs. It is extremely dangerous to touch with a high cancer probability for anyone who handles it. Could you please give more details about your question?
Calcium, sodium and hydrogen to name a few.
Nitrogen react with the majority of other chemical elements.
If you mean the inner core of the star, that will initially be the same as the remainder of the star - mainly hydrogen, and a small amount of helium. As the star burns up the hydrogen, the amount of helium will increase. Once there is not much hydrogen left, the star will get hotter, and burn helium, converting it into heavier elements.
Almost any element, including the heavier noble gases, can form a molecular compound (if chelated cations are considered molecular as most chemists would), but the vast majority of such compounds are composed of nonmetals.
hydrogen,All stars are composed primarily of hydrogen. Stars can also contain some other elements such as helium, but hydrogen accounts for the majority of a star's composition.
Air is composed of non-metals (Nitrogen, Oxygen, Carbon Dioxide, Hydrogen, assorted Noble Gasses), as is water (H2O), and the majority of living matter (Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorous)
Carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and phosphorous (P) are the main elements. Other important "players" are sulfur (S), sodium (Na), calcium (Ca), and magnesium (Mg).
Plutonium is a reactive metal and can react with the majority of other chemical elements: hydrogen, oxygen, halogens, carbon, sulfur, nitrogen, selenium, boron, phosphorous, silicon, etc.
Hydrogen and Helium
Berkelium has the electronegativity 1,3 in the L. Pauling scale; it is sufficiently reactive to react with the majority of other elements but the chemistry of Bk is not so studied because Bk is very rare. Compounds with oxygen, halogens, hydrogen, nitrogen, sulfur, arsenic, phosphorous, etc. are now known.

The percentages vary quite a lot from one star to another. The general tendency, however, is that the majority of stars contain a large percentage of hydrogen. In general, hydrogen is the most abundant element in the Universe - for now. In the future, it will gradually be used up, and there will be less hydrogen, and more of the heavier elements.
Plutonium combines with oxygen, carbon, and fluorine to form compounds which are used in the nuclear industry, either directly or as intermediates.Plutonium is a reactive metal and can react with the majority of other chemical elements: hydrogen, oxygen, halogens, carbon, sulfur, nitrogen, selenium, boron, phosphorous, silicon, etc
All of them - but mostly hydrogen & helium.
