A hydrogen bond forms between molecules that contain hydrogen bonded to?
electronegative atoms like oxygen, nitrogen, or fluorine. This bond is a weak attraction that occurs when a hydrogen atom covalently bonded to one of these electronegative atoms is attracted to another electronegative atom nearby.
What atom has a tendency to attract electrons?
Francium. It's outer shell is far enough away from the nucleus with its opposite, repelling positive charge which makes it difficult to exchange electrons. And its outer shell is incomplete.To put it another way, of all the atoms that are missing an electron from their outer energy level, Francium is the one that has the least influence from the nucleus because its outer energy shell is the furthest away from the centre, so it is happiest to receive electrons.
What is the name of electrons in the outermost shell that an atom can gain lose or share with another atom?
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
Why flourine is most reactive?
The thing that makes fluorine so reactive is its electronegativity.
How many electrons would fluorine have to gain or lose too become stable?
Fluorine has 7 valence electrons. In order to become stable, Florine will share 1 electron with another atom to get 8 electron and become stable.
What is an electronegative?
An electronegative atom is an atom that can attract a bonding pair of electrons from another atom. Fluorine is the most electronegative element.
What is an electronegative atom?
An electronegative atom is an atom that has a strong attraction for bonding electrons in a chemical bond. Examples of electronegative atoms include fluorine, oxygen, and nitrogen, which tend to pull electrons towards themselves when they form bonds with other atoms.
Can fluorine form a nonpolar covalent bond?
No, fluorine typically forms polar covalent bonds due to its high electronegativity. Fluorine is the most electronegative element on the periodic table, so when it bonds with another element, it attracts electrons towards itself, resulting in a polar covalent bond.
Why does fluorine always have an oxidation number of -1?
Fluorine is the most electronegative element, so it tends to attract electrons strongly and form a single covalent bond with one electron from another element. This results in a stable electronic configuration, leading to an oxidation number of -1.
Why is fluorine most electronegative than oxygen?
Electronegativity is an atoms relative ability to remove an electron pair in the formation of a covalent bond. I.e. an atoms ability to steal a pair of electrons from the outer ring of another atom to make a covalent bond, (like a contract to share electons in order to fill there outer shells and become stable) Across the periodic table (left to right) this gets harder to do due to an increase in attraction forces between the nuclear charge and the outer electons. Therefore across the periodic table 'more' electronegativity energy is required to remove those electrons. Down the periodic table, from top to bottom attraction forces between the electrons in the outer shell and the central nuclear charge decreases (shielding effect of sub levels and increased atomic radius), this make it easier for the electrons to be stolen, so there is less electronegativity required. Fluorine is the highest and furthest to the right, making it the most electronegative. (Helium and Neon etc have full outer shells so arent involved in covalent bonds)
A hydrogen bond forms between molecules that contain hydrogen bonded to?
electronegative atoms like oxygen, nitrogen, or fluorine. This bond is a weak attraction that occurs when a hydrogen atom covalently bonded to one of these electronegative atoms is attracted to another electronegative atom nearby.
When fluorine bonds with another element the electrons do what?
Well, when fluorine bonds with another element, the electrons like to share and play nicely together. They form a strong bond by sharing electrons, creating a stable and happy relationship. It's like a beautiful dance between the atoms, creating a lovely and balanced molecule.
What type of bonds can fluorine create and why?
Fluorine can create covalent bonds because it is highly electronegative and prefers to share electrons with other atoms. It can also form ionic bonds by gaining an electron to achieve a full outer shell.
Why is fluorine more electronegative than chlorine?
A qualitative answer is that fluorine is more electronegative than chlorine because the outer electrons in fluorine are less "screened" from their attraction to the positive nucleus, because there are more non-valence electrons in chlorine.Two factors affect the electronegativity of an element:Nuclear charge: If the element has a large nuclear charge it will attract electrons to it more readily than one with a small nuclear charge.The radius of the atom: If the element is small then the effect of the pull from the nucleus will be greater (due to physical distance between the nucleus and the outside of the atom and the effect of electron shielding - shells of electrons reducing the 'pulling' power of the nucleus). As we go across a period the atomic radii of the atoms decreases. As we go down a group the atomic radii of the atom increases (even though the nuclear charge also increases, the atomic radii increases to a greater extent which practically cancels out the effect of the increased nuclear charge)Therefore the most electronegative element is Fluorine, followed by Oxygen, Nitrogen and Chlorine: F>O>N>C
Is C6h6 capable of hydrogen bonding?
No, benzene (C6H6) does not have hydrogen bonding capabilities as it lacks hydrogen atoms directly bonded to highly electronegative atoms like fluorine, oxygen, or nitrogen. Hydrogen bonding requires a hydrogen atom bonded to a highly electronegative atom and a lone pair of electrons on another electronegative atom.
Why is FCl polar but F2 is not?
A molecule is polar is a result of differences in electronegativity; that is, one atom has a stronger pull on electrons than another. Flourine (F) is more electronegative than chlorine (Cl), and so tends to pull electrons to its side of the molecule. This makes FCl polar. F2 consists of two atoms of fluorine, which are identical and thus have the same electronegativity. Therefore, the molecule is nonpolar.
What atom has a tendency to attract electrons?
Francium. It's outer shell is far enough away from the nucleus with its opposite, repelling positive charge which makes it difficult to exchange electrons. And its outer shell is incomplete.To put it another way, of all the atoms that are missing an electron from their outer energy level, Francium is the one that has the least influence from the nucleus because its outer energy shell is the furthest away from the centre, so it is happiest to receive electrons.
