2 electrons in the n=1 orbit 6 electrons in its n=2 orbit 8 protons in nucleus 8 electrons 6 electrons 4 electrons shared Covalent bond exist between the two oxygen atoms
The n = 1 means the first shell of an atom whereas n = 2 means the second shell of an atom and so on.
As every atom consists of three sub-atomic particles which are protons, neutrons and electrons.
Protons and neutrons reside inside the nucleus of an atom and electrons revolve outside the nucleus of the atom.
A covalent bond is defined as the bond formed by sharing of electrons between the two combining atoms.
Therefore, the given questions are answered as follows.
There are 2 electrons in the n = 1 orbit of each atom.
Each atom has 8 electrons in its n = 2 orbit, after the sharing of electrons take place between both the oxygen atoms.
Each atom has 8 protons in its nucleus.
Each atom has 8 total electrons.
There are 6 electrons in oxygen's outer shell before sharing electrons.
There are 4 electrons being shared between the two atoms.
Double bonds exist between the two oxygen atoms. This is because sharing of two electrons is taking place. Hence, a double covalent bond exists when two oxygen atoms when they chemically combine together.
I believe the most appropriate answer would be to change the core from wood to iron. This is because iron is a magnetic material while wood is not magnetic hence cant acquire magnetism. Other factors that would increase the strength of electromagnet would be; increasing the amount of electric current, and increasing the number of windings.
