Noble Gases
No, oxygen is not given off when group 1 elements react with water. Instead, these reactions typically result in the formation of hydroxide ions and hydrogen gas.
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
React a small ammount with water and compare the heat given off with other alkali metals ofc if it does not react then it would be Cs
When two compounds react, they can form new compounds and/or elements. In many chemical reactions, the compounds involved undergo rearrangement of atoms to form new compounds. In some cases, chemical reactions may also involve the release or absorption of elements such as oxygen, hydrogen, or carbon dioxide.

Shape
Group 8A, the noble gases because they have high electron affinity.
Europium is the most active of the lanthanides. it reacts quickly with water to give off hydrogen. it also reacts strongly with oxygen in the air, catching fire spontaneously. Scientists must use great care in handling the metal.
The elements in group one and two react so easily because they have only one or two valence electrons, and the non metals, want those electrons. These group elements loose 1 or 2 electron to be stable instead of gaining 6 or 7 to complete the outer shell attain stable electronic configuration of a noble gas.
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).
cross-functional
Group 4 (previously called IVA) elements all have two valence electrons, and have high boiling points. A possible exception is rutherfordium, the chemistry of which is not well-known due to its instability.
