Answer:
Oxygen cycle
Explanation:
The components of the reservoirs of oxygen that are exchange in our environment is the oxygen cycle
It suggests the movement of oxygen between the living and non-living parts.
- The cycle does not account for oxygen that is trapped and cannot be exchanged in nature.
- Oxygen is important component of the atmosphere.
- Gaseous exchange between living organisms and atmosphere involves oxygen to a very large extent.
The number of valence electron information on the periodic table is used to complete electron dot diagrams. One can obtain the number of valence electron information on the periodic table by determining the column number of the periodic table. The first column number has 1 as the number of its number of valence electron and so on.
Answer:
A the gravitational potential energy gained by a stone lifted through the same
Periodic table is a table that arranges elements based on physical and chemical properties into groups and periods. Non metals reacts by gaining electrons, the ease of gaining electrons determines the reactivity of a non metal. Argon and helium belong to group eight of the periodic table therefore are unreactive (inert), carbon belongs in group thus reacts by gaining 4 electrons while fluorine is a group 7 element and reacts by gaining 1 electron. Therefore, the answer is fluorine,since it requires to gain only one electron.
