When reactive elements combine they give off heat and what other substance?
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.
What elements easily give up electrons?
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.
What do most people not know about oxygen?
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.
Why does copper give off no hydrogen when reacting in water?
because it isn't a reactive metal
Water and carbon dioxide in leaves combine to make what?
They combine to make sugars & starches and give off oxygen as a waste product
What do elements give off when they are heated?
Electromagnetic radiation.
What colour does calcium give off?
fireworks and elements
What is chemicals contained in bodies of animals that give off lights when combine with oxygen?
dumbledore
What are unstable elements that give off energy as they decay called?
The elements described are said to be radioactive.
What does the spectroscope do?
is an instrument which identifies the elements by the color that they give off
What do spectrograph do?
A spectroscope identifies the elements by the color that they give off.
Reactivity of s-block element?
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.
