This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
No because if the body never met the pathogen before so the immune system would not have had any reason to make an antibody against it because body makes antibodies against specific pathogen :)) i hope this be helpful
The reason the answer is sugar is because when plants go through photosynthesis they produce sugar which is called glucose. This glucose gives the plant energy to produce oxygen and continue living.
Yes, this is true because some bacteria in our environment tends to either fend off of or kill other types of bacteria. In this case, this bacteria is helpful because it turns gaseous nitrogen into a form that can be absorbed and used by plants in our environment.
