Why chemistry, why again?

Why chemistry, why again?. You are made up of biomolecules! Your biomolecules are built from food you eat Your body breaks them down and rearranges them to give you: Energy and Building blocks for proteins, carbohydrates, lipids and Nucleic acids (DNA, RNA). You are what you eat!.

Molecular Geometry and Polarity

Molecular Geometry and Polarity. Molecular Shapes. Molecular shape determines chemical and physical properties Electrons repel each other resulting in the molecular shape Lone pairs are not shared between protons and therefore repel slightly more. Hybridization. Atomic orbitals mix

Chemical Bonding

Chemical Bonding. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds? Atoms will form a chemical bond if their potential energy is lowered in doing so. Describe the difference between ionic and covalent bonding.

Chemistry

Polar vs. Non-polar Molecules. Chemistry. Molecular Polarity. Just like bonds can be polar because of un-equal electron distribution, molecules can be polar because of un-equal electron cloud distributions These imbalances are not the same as ion formation.

Molecular Polarity

Molecular Polarity . Chemistry. Polar vs. Non-Polar Molecules. Polarity in a molecules determines whether or not electrons in that molecule are shared equally. When determining the polarity of a molecule, it is all about symmetry. Asymmetric molecules tend to be polar.
