Generally speaking 'like dissolves like' so when you thinking if a molecule can dissolve in a particular solvent, you need to decide what type of bonding that solvent can exhibit and what bonding the molecule in question exhibits. So for example water can exhibit hydrogen bonding. This means for something to be able soluble in water, it too needs to be able to exhibit hydrogen bonding. Methane only contains hydrogen and carbon and thus, will not exhibit hydrogen bonding. However, methanol has carbon, hydrogen and oxygen and therefore, can exhibit hydrogen bonding. As a result, using the 'like dissolve like' approach we can see why methane will be insoluble in water but methanol will be soluble.
When you join one atom of hydrogen and one atom of helium, you get a molecule with the chemical formula HHe. This is not a stable combination as the resulting molecule is highly reactive due to the different properties of hydrogen and helium atoms.
You need 1 oxygen atom for every 2 hydrogen atoms. If you're getting your pure gases in tanks of equal pressure you will thus need twice as many H tanks as O tanks. But because Oxygen Atoms weight alot more it will be a greater mass of O. if you have to much hydrogen you would make an acid
Neon does not occur as a diatomic molecule. Its atoms exist as single atoms due to their stability and lack of a need to form covalent bonds with another atom to achieve a full valence electron shell.
It'll form either one (if something else is bonding to the oxygen atom) or two (if you're making water, in which case you need two hydrogen atoms).
The primary attractive forces that need to be overcome to dissolve CsI in HF are ionic bonding between Cs+ and I- ions in CsI and hydrogen bonding between HF molecules. Ionic bonding involves the strong electrostatic attraction between oppositely charged ions, while hydrogen bonding involves the attraction between the partially positive hydrogen atom in HF and the partially negative fluorine atom in another HF molecule. Applying energy through stirring or heating helps disrupt these attractive forces and allow CsI to dissolve in HF.
One atom is needed to full the outer shell of a hydrogen atom, this is bacuse in GCSE terms electrom structure goes 2,8,8,2 and hydrogen only has one shell, so it would need 2 to complete this shell. This is the same for A-level however we refer to electron structure in spd, the electron structure of hydrogen then would be 1s1.
Electrons are shared- giving each atom a share of 8 electrons. Note that this "rule" does not work for hydrogen as only two electrons need to be shared to give each H atom the electronic configuration of He, helium.
I believe that the answer is "Diatomic."The answer you are looking for can be found in the link belowhttp://dl.clackamas.cc.or.us/ch104-08/elements.htmElementsSome differences between covalent and ionic bonding have already been mentioned. Here is another one. It is possible for covalent bonding to occur between atoms of the same element. That is not possible with ionic bonding. With ionic bonding you need to have two different elements, one to lose electrons and one to gain electrons. The atoms involved in covalent bonding all need to gain electrons and they do not have to be different elements. So let's look at covalent bonding in pure elements.Let's start with the simplest case, a hydrogen atom bonding to another hydrogen atom. Each has one electron and wants one more. By coming together, each can "gain" one electron from the other. Since neither atom lets go of its electron, the two atoms are bonded together by their mutual attraction for the shared pair of electrons.H2 is an element because it contains only hydrogen atoms. H2 is a molecule, no additional bonding is needed. There are two atoms in the molecule so it is a diatomic molecule. Hydrogen is one of several elements that form diatomic molecules.These are the list of diatomic molecules.Hydrogen H2 | Nitrogen N2 | Oxygen O2 | Fluorine F2 | Chlorine Cl2 | Bromine Br2 | Iodine I2 | Astatine At2 | Phosphorus P4| Sulphur S8
The chemical formula for water (H2O) indicates that each water molecule contains two hydrogen atoms and one oxygen atom. This is because oxygen needs two additional electrons to complete its outer electron shell and achieve stability, while hydrogen needs one. By sharing electrons with two hydrogen atoms, the oxygen atom can achieve a full outer electron shell through covalent bonding.
At least two: 1 proton + 1 electron = Hydrogen atom

Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
2, but its an isotope of hydrogen with a mass of 2 rather then 1.09
Bonding can discolor, creating a cosmetic concern. Bonding can chip, fracture, or otherwise break, exposing parts of the tooth that need to be covered. Bonding can wear out just through normal usage over time. More dental decay can occur on the same tooth, requiring the old bonding to be replaced.
