The elemental classification for oxygen would be non-metal. It is located in period number 2 and group number 16. It has an atomic number of 8. At room temperature, it exists as a gas. Hope this answers the question. Have a nice day.
Elements are distributed into 7 period and 18 Groups in a periodic table.
Elements are classified into three categories:
<u>Metals:</u> They are called as metals because they loose electrons to attain stability. These elements belong from Group 1 to group 13 of the periodic table. They are hard and are mainly solid.
<u>Non-metals:</u> They are called as non-metals because they gain electrons to attain stability. These elements belong from Group 15 to group 17 of the periodic table. They are soft and are mainly liquid or gases.
<u>Metalloids:</u> They are called as metalloids because they show properties of both metals and non-metals. These elements belong from Group 14 of the periodic table.
Oxygen belongs to Group 16 and period 2 of the periodic table.
Lysosomes contain digestive enzymes which are used for digestion of food and dead organelles. It fuses with a vacuole which contain the targeted material(food or dead organelles) and digests the material inside it
Since the speed in which the gas molecules are faster as they are heated, they fly around in the container and logically, it is harder to insert a moving object into water than something more stationary or slower.
