Why has water a polar covalent bond?
"Polar-covalent" is how chemists say that the bond in question is not massively polar, ie the bond isn't easily broken when placed in a polar solvent, but nor is the bond completely covalent (more or less equal sharing of bonding electrons between involved atoms). In short, a polar-covalent bond has electrons which spend more time near one atom than another, but not so much that the bond is polar or ionic.Now for the why: Electronegativity. The difference in electronegativities (EN) between two atoms is a huge factor in determining where the bonding electrons like to spend their time (recall, EN is a measure of "how badly" an atom wants to hold onto electrons when bonded or in a molecule). Oxygen has an EN of about 3.5 and hydrogen about 2.2. Just from this you can see that the oxygen atom is wants electrons more than hydrogen does. The difference here is 1.3. As a general rule of thumb, if the difference in EN's in a particular molecular bond is greater than about 1.5 or 2, the compound is probably ionic. eg for NaCl the difference in EN's is 2.23 (ionic), and for CH4 it's 0.35 (covalent).
Is ch4 molecule polar or non polar?
non polar
Are Hydrogen bonds are ionic bonds?
Hydrogen forms some ionic and some covalent bonds - depending on its partner EN for H is 2.2 En increase across the rows in the periodic table Ionic bonds form between compounds with large differences in EN Colalent bonds form between molecules with similar ENs so (As a general rule of thumb) going across the periodic table it will first form ionic bonds then covalent molecular
Why is water a polar covalent?
In each water molecule oxygen attracts more than its "fair share " of electrons that forms a partial negative charge on oxygen and partial positive charge in hydrogen. So it is polar. Oxygen has more protons than hydrogen, which attract an equal number of electrons. Oxygen and Hydrogen originally bonded to fill their valence shells. Now that the covalent bond is formed, the oxygen "hogs" the electrons.
Why is the covalent bond between O and H considered polar?
Oxygen has an electronegativity of 3.44 Hydrogen has an electronegativity of 2.2 So Oxygen attracts the electrons so the oxygen side of the bond is more negative as the electron are closer to it, this forms permanent dipoles as parts of the molecule are have opposing charges. And that is a polar covalent bond and non polar bond is is where you have two elements with the same EN and the electron is equidistant from them. You can have non polar molecules with polar bonds for example carbon dioxide whitch is linear in shape so the charges cancel each other out.
What is the prefix for hydrogen?
en is the prefix.

What is the atomic mass for hydrog en?
Hydrogen is a non meta element. Atomic mass of it is 2.
What does EN stand for in the periodic table?
EN in the periodic table stands for Electronegativity. Electronegativity is a relative measure of an atom's ability to attract shared electrons to itself when it is chemically bonded with another atom.

What particle is emitted in beta radiation?
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.
What is required for two atoms to share electons equally in a chemical bond?
the electrons are shared equally between two atoms because they need eight electrons on the valence(last) shell so that the elements can reach a state of stability. The idea here is to have the elements have the same amount of electrons on the last shell as those in the noble gas group. Let's consider covalent vs. ionic bonds to see what the difference is. We say a bond is ionic when electrons spend much more time around the more electronegative element. That is, we classify the bond type based on the electronegativities of the participating elements (Electronegativity is a measurement of an element's ability to 'steal' electrons). We say that a bond is ionic when the difference in electronegativities is around 0.5 or more. ENhigh - ENlow > 0.5 ----- Ionic bond ENhigh - ENlow < 0.5 ----- Covalent Bond Sodium has EN = 0.9. Chlorine has EN = 3.0 3.0 - 0.9 = 2.1, NaCl is an ionic bond Carbon has EN = 2.5. Hydrogen has EN = 2.1 2.5 - 2.1 = 0.4, CH4 has covalent bonds
How Electrons are transferred?
electrons are transfered from one atom to another when it is negatively or positively charged. this is done so that the atom can be come stable. for an atom to become stable the amount of electrons on the orbital must be equal to the amount of protons so that atom would have no charge.
