This is an exothermic reaction.
Fluorine is too strongly electronegative to donate electrons to any other atom.
Fluorine has higher electron affinity than any other element.
As you did not specify an isotope of cesium, I will assume you meant natural cesium. Natural cesium is not radioactive so it does not decay. There will always be the same 10 g of cesium, no matter how long you wait.

Fluorine.
The single "most likely" element that would form an ionic compound with fluorine is cesium, or possibly francium if enough of it could be collected. This is because cesium, among stable elements, has the lowest electronegativity and fluorine has the highest electronegativity. However, any alkali or alkaline earth metal element in fact readily forms an ionic compound with fluorine, as do many other metals.
Fluorine is a halogen. It shows only -1 when combined with other elements.
Tetrafluoride is a chemical made of four fluorine atoms. It is often combined with other elements such as carbon. This CF4 is used as a refrigerant.
Like other metals cesium loses electrons.
The standard atomic weight for cesium is 133. There are 3 other radioactive cesium isotopes that have atomic weights of 134, 135, and 137. Cesium 133 is the only one that is found in nature. The other isotopes are synthetic.
Not in all uses. Some inorganic compounds of fluorine are used in toothpaste for example. Fluorine compounds are contained in the teeth and in the bones of people and animals. PURE fluorine is an extremely deadly poison that is very corrosive and explosive, such as when it contacts anything containing hydrogen. Fluorine will take your hide right off, blind you, and kill you. When a person asks the question "Is fluorine a poison?", they MEAN pure fluorine, so answering the question in any other way is rather silly. Some other pure elements that are deadly poisons include chlorine, sodium, magnesium, cesium, potassium, bromine, cadmium, mercury, phosphorus, selenium, tellurium, radon, and plutonium. Don't mess around with any of these.
No. Cesium and hydrogen are both elements. No element contains any other element.
No. Cesium reacts with a number of nonmetals, bu not with other metals or metalloids. Cesium is a powerful reducing agent and will react strongly with oxidizing substances.
Fluorine (F) has only this name.
All the alkali and alkaline earth metals: Li, Na, K, Rb, Cs, Fr, Ra, Ba, Sr, Ca, Mg, and Be. Most other metals would also form an ionic compound with fluorine.
neon
The salts in Fluorine are called fluorides, and fluorine reacts with all other elements except oxygen, neon, helium, and krypton.
