The diatomic oxygen has been more stable than the atom of oxygen due to the presence of a covalent bond.
The oxygen has been the nonmetal with 6 valence electrons. In order to attain a stable configuration, oxygen has to gain 2 electrons.
The elemental oxygen present in nature has been diatomic oxygen. The diatomic oxygen has been formed by the sharing of the 2 electrons of each atom resulting in the formation of the covalent bond.
The covalent bond formation helps the oxygen atom to attain the noble gas configuration. Thus, diatomic oxygen has been more stable than atomic oxygen.

Answer:
Both atoms in an O2 molecule have achieved a noble gas electron configuration. – An oxygen atom does not have a stable octet of valence electrons.
Explanation:
The correct answer is B. Lindsay measures the sizes of the craters on the Moon, is the best description of a person doing science.
Science is the practical and intellectual pursuit of the understanding of the physical and natural world that surrounds us. It involves a systematic study: observation, experimentation, data analysis, discussion and conclusion. Science is the human effort to gather knowledge about the universe.
Answer:
B.
Explanation:
C6 H12 O6 + 6 O2 + 6 CO2 + 6 H2O
Answer:
C₆H₁₂O₆ and O₂ are reactant.
CO₂ and H₂O are products.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Explanation:
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
Steps involve in anaerobic respiration are:
Glycolysis
Glycolysis is the first step of both aerobic and anaerobic respiration. It involve the breakdown of one glucose molecule into pyruvate and 2ATP.
Fermentation
The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced, however carbon dioxide is released in this step.
Non-examples of deposition, weathering, and erosion are the geological processes in which earthen substances or materials are broken down or transported by natural forces like gravity, wind, rainwater, and air.
Non-examples of deposition, weathering, and erosion are:
Therefore, some of the non-examples of the geological processes are wind, air, and gravity.
