C (Carbon) has a charge of 4+, while H (Hydrogen) has a charge of 1+. Both elements have a positive charge, but hydrogen is technically more negative.
An S atom has the weakest attraction for the electrons in a bond with an H atom.
In methane a C atom is surrounded by 4 H atoms.Now about the angle. There are 6 tetrahedral angles i.e H-C-H angles..Imagine a C atom in the center.A H atom on top of it and 3 H atoms below forming a triangle(to make it look simple).Now start from the H atom on top,go through the C atom to an H atom below.This way you get 3 tetrahedral angles right??Now start from an H atom below the C atom and go to another H which is below the C atom via C atom(keep this H atom in mind).This way you get 2.Now for the last angle.Simple.Its the angle between the remaining 2 H atoms in the bottom.Hope you got it. Mathematically,number of ways we can select 2 H atoms from 4. 4c2,which equals 6.
The Lewis structure for methanol (CH3OH) consists of a carbon atom bonded to three hydrogen atoms and one oxygen atom. The carbon atom is in the center with single bonds to the three hydrogen atoms and one bond to the oxygen atom. The oxygen atom has two lone pairs of electrons.
The Lewis structure for N2H2Cl2 consists of two nitrogen atoms bonded together by a triple bond, each nitrogen atom is bonded to a hydrogen atom, and each nitrogen atom is also bonded to a chlorine atom. There are no lone pairs on any of the atoms.
H (Hydrogen)
Positive ion. Examples: H+ Na+ Li+ Be+ N+ Lost multiple electrons? H2+ Na2+ Li3+ H5+
C (Carbon) has a charge of 4+, while H (Hydrogen) has a charge of 1+. Both elements have a positive charge, but hydrogen is technically more negative.
Short Answer: a partially positive hydrogen atom gets attracted to a partially negatively charged atom. _______________________ Take water for example. There is an Oxygen atom (which pulls electrons towards it-- making it partially negative) There are also two hydrogen atoms. The (negatively charged) electron on each H atom is being pulled towards the O atom, making the Hydrogen partially positive. Now, when two water molecules come together, the partially positively charged H's on one water molecule are attracted to the partially negatively charged O's on the other molecule. This attraction between oppositely charged atoms on different molecules creates a 'hydrogen bond'.
No, the former answer (striked through below this) is very wrong!Hydrogen (elemental H atom) contains only 1 (one!) electron (1s1) and since a H ion (H+) has lost that one to become stable, this H+ ion has no (zero!) electrons at all.Only the very rare and exceptional, negatively charged hydride ion H- ion contains two electrons (1s2 configuration, not favoured, not enough electronegativity)Yes. A Hydrogen atom "wants" to be stable, so it gains an electron to be iso-electronic with helium. After that, its electron configuration is 1s2. H+
The size will be H- ion > H atom > H+ ion
H2O ionized to.... H + ( a proton, a stripped of it's electron hydrogen atom and a cation. Positive charge ) OH - ( hydroxide polyatomic ion and an anion. Negatively charged. )
An S atom has the weakest attraction for the electrons in a bond with an H atom.
A hydrogen bond can form between a hydrogen atom of one molecule and an electronegative atom (such as oxygen, nitrogen, or fluorine) of another molecule. This bond is a weak attraction between the partially positive hydrogen of one molecule and the partially negative region of the electronegative atom of another molecule.
H has exactly one atom of hydrogen.
