heat,friction,turbulance and electricity
Heat is energy, not a substance. When reactive elements combine they form more stable compounds. The exact substance formed depends on the elements. e.g. hydrogen and oxygen form water while sodium and chlorine form common table salt.
Group 1 elements, such as lithium, sodium, and potassium, easily give up electrons because they have one electron in their outer shell and are highly reactive. Additionally, elements in Group 17, such as fluorine and chlorine, can also easily gain electrons.
It is what causes you to age, it is essential for ATP production (what your body uses for 100% of its fuel), it is one of the most reactive elements in existence, and last but not least plants do not give off Oxygen and not CO2 in photosynthesis/Respiration they give off both.
because it isn't a reactive metal
They combine to make sugars & starches and give off oxygen as a waste product

The elements described are said to be radioactive.
is an instrument which identifies the elements by the color that they give off
A spectroscope identifies the elements by the color that they give off.
S-block elements are highly reactive due to the presence of one or two electrons in their outermost electron shell. These elements readily donate or lose these electrons to achieve a stable electron configuration, resulting in strong reactivity with other elements. The reactivity of s-block elements generally increases down the group.
