A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.
Answer : According to the octet rule, sodium wants to lose an electron.
Explanation :
The given element is sodium with atomic number 11 that means it has 11 electrons.
The electronic configuration of sodium will be,
From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.
According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).
Hence, according to the octet rule, sodium wants to lose an electron.

When two different bird species temporarily occupy the same niche, they would most likely competewith each other.
What is the competition?
Is the struggle for limited resources between two organisms.
They compete with each other for food, shelter, space, a mate, etc.
Survival for the fittest
When two organisms temporarily occupy the same resources they will compete with each other.The most suitable organism will survive by nature. This is known as survival for the fittest.
Survival of the fittest states that organisms best adjusted to their environment are the most successful in surviving and reproducing. Competition is a major part of the survival of the fittest by Darwin's evolution theory.
Thus, we can state that competition will take place between 2 different bird species.

The advantage of an electron transport chain is that a small amount of energy is released by the transfer of an electron between each pair of intermediates.
Cellular respiration has three stages: glycolysis, the Krebs cycle and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons through a series of intermediates is used to create an electrochemical proton gradient across the inner mitochondrial membrane.
As the electrons move in the transport chain, a small amount of energy is released, which is coupled to the active transport of protons into the mitochondrial inner-membrane space.
Subsequently, this proton gradient is then used to synthesize ATP by an ATP synthase.
In conclusion, the advantage of an electron transport chain is that a small amount of energy is released by the transfer of an electron between each pair of intermediates.
