What makes a covalent bond different from an ionic bong?
The most obvious difference is that covalent bondingoccurs between non-metals, whereas ionic bondingoccurs between a metal and a non-metal.Covalent bonding is also a bonding process which shares electrons, whereas ionic bonding is a bonding process in which electrons are transferred. This would therefore also affect the way in which you draw dot and cross diagrams for a covalent compound versus an ionic compound.
How does a lone pair contribute to the molecular shape?
Lone pairs do not affect the shape of diatomic molecules, and Lone pairs are electrons that are not in bonds. Lone pairs do not affect the shape if they are not on the central atom.
How do periodic trends affect bonding?
Periodic trends affect bonding due to the arrangement of the elements on the periodic table. The periodic table only includes chemical elements.
Why does the presence of lone pairs contribute to the polarity of a water molecule?
How do lone pairs around the central atom affect the polarity of the molecule?
How is hydrogen bonding among water molecules related to the strcture of the water molecule?
A hydrogen bond is an intermolecular bond between a hydrogen attached to an electronegative atom (N,O, F, etc) on one molecule and an atom with a lone pair of electrons on another atom. These bonds are much weaker than a covalent bond. Nevertheless, they can greatly affect the properties of a substance and are responsible for water's unique attributes. In water, hydrogen bonds exist between the hydrogen on one water molecule and the oxygen on another.
How do electrons shells affect the ability of elements to bond?
The external electron shell is responsible for the formation of chemical bonds.

What are the structural effects of organic compounds?
There are six structural effects that affect the stability, acidity/basicity, melting point,volatility and solubility of an organic compound. These are VAN DER VAALS, RESONANCE, H-BONDING, CH-HYPERCONJUGATION, STERIC EFFECT, and INDUCTIVE EFFECT. VAN DER WAALS is the attractive or repulsive forces between molecules (or between parts of the same molecule) other than those due to covalent bonds or to the electrostatic interaction of ions with one another or with neutral molecules. (source, wikipedia) RESONANCE is the delocalization of the PI bonds. This adds to the stability of the compound. H-BONDING or hydrogen bonding is the bonding of Hydrogen atoms to an electronegative atoms (i.e. O) H-bonding can be intramolecular or intermolecular. When a compound is capable of H-bonding, the forces of attraction involved is stronger. CH-hyperconjugation is also known as sigma-electron delocalization. The sigma electron delocalization takes place towards the sp2 hybridized atoms. STERIC EFFECT is the effect of BULKINESS in a molecule. INDUCTIVE EFFECT is when the electron cloud is DISTORTED: Towards the electronegative part of the molecule (electron-withdrawing) away from the electron repelling groups (electron-repelling) Anonymous
How does the number of electrons in energy levels affect bond formation?
Chemical bonding is occurred from the participation of valence electrons. Valence electrons are located in the topmost energy level of an atom.
What happens to electrons after a chemical bond is formed?
If the starting point are elements then the inner shell electrons (non valence) these orbit the nuclei of the atoms and the formation of a chemical bond does not affect these materially. What happens to the valence electrons depends on the bond formed. In an ionic bond electrons are transferred from say the metal atom to the nonmetal- these electrons essentially "orbit" the nuclei of the cations and anions. They are "localised". When a covalent bond is formed the valence electrons involved are shared between the atoms, they "orbit" both nuclei. When the bond is polar covalent they spend a little more time nearer the more electronegative element. When a "delocalised"covalent bond is formed as in bezene or graphite the electrons orbit a number of atomic nuclei. In a metallic bond the valence electrons are also delocalised (the sea of electrons model) across the metal lattice, but in transition metals there is additional bonding between electrons in d orbitals (the tight bound electrons) and these electrons are essentially localised.
How do you do ionic bonding with isotopes?
Being an isotope doesn't affect bonding at all. Isotopes only affect nuclear transformations (AKA radioactive decay) while bonding is affected by the valence shell of electrons (the outer layer). This is also why the nucleus is ignored by most of the chemists (other than the specialized nuclear chemists of course).
Why are valence electrons significant?
They are significant because they determine what element would be in a specific block (s,p,d,f).
How the structure of aluminium affect its properties?
well because of the free electrons in the structure of aluminium it is able to allow the passage of electron from electric current due to disassociated electrons in its structure basically because of the metallic bonding and the free electrons present it can conduct electricity and heat.
How does a lone pair contribute to the molecular shape?
Lone pairs do not affect the shape of diatomic molecules, and Lone pairs are electrons that are not in bonds. Lone pairs do not affect the shape if they are not on the central atom.
How does hydrogen bonding affect thermoplastics?
no
What is the outer most energy level of an atom?
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
How does the number of valence electrons that carbon has affect the number of bonds that carbond can form?
if the number of electrons are greater in energy levels or shell so greater will be the nuclear attraction because of greater nuclear attraction the atom will be greatly able to attract other atoms towards their self and easily form bond between them..
