Answer:
Neon
Explanation:
The most stable Atoms are from the elements on group 18 of the predictable.
Answer:
Microorganisms which are killed in the presence of normal concentrations of atmospheric oxygen are called obligate anaerobes.Some species are capable of surviving in upto 8% while other losing viability in 0.5%.They survive without oxygen as they use other molecules as electron acceptor instead of oxygen.
Explanation:In aerobic organisms oxygen is used in cellular respiration as an electron acceptor.oxygen accepts electrons and turns into water H2O or CO2.While obligate anaerobes other molecules as their primary electron acceptors.common electron acceptors used by them are Nitrate NO3-, Sulphate SO42- or sulphur S,Iron,mercury and manganese.So in this way they undergo respiration and survive without oxygen.
Magnesium + oxygen = magnesium oxide

1. H₂S and H₂Se exhibit the following intermolecular forces dipole-dipole forces and dispersion forces. Hence, both the molecule possess certain dipole moment and they interact with each other. The dispersion force is also known as London force, and this is the weakest intermolecular force.
2. Therefore, when comparing H₂S and H₂Se, the one with a higher molar mass has a higher boiling point. As one knows that high molecular mass means that more energy is needed.
3. The strongest intermolecular force exhibited by H₂O is hydrogen bonding.
4. Therefore, when comparing H₂Se and H₂O, the one with stronger intermolecular forces has a higher boiling point.
