atoms and more

what is polarity polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multiple moment
what is cohesion the sticking together of particles of the same substance
what is admission the force of attraction that causes two different substances to join
what is universal solvent water can desolate other substances
what is the chemical formula for water H2O there are 2 hydrogen molecules and 1 oxygen molecule. the bond is a hydrogen bond
what are the elements of carbohydrates oxygen, hydrogen, carbon monomer: glucose, fructose, molscarride polymer: large molecule formed by smaller molecules stick together E.G.: monasecharride
what are the elements in lipids carbon, hydrogen, oxygen monomer: any fatty substance or oils polymer: saturated fatty acid there's saturated and unsaturated E.G. C57 H110 O6
what is the elements in proteins carbon, hydrogen, nitrogen, sulfur ( sometimes) monomer: DNA or RNA create proteins polymer: peptide bonds
what is the elements of nucleic acids oxygen, hydrogen, carbon, nitrogen, phosphorus employer: nucleotides genetic code for all organisms * phosphorus is what makes up DNA.
what is an electron a electron is a negativity charged particle that orbit that nucleus of an atom
what is a proton a proton is a positively charged particle that is inside the nucleus
what is a neutron a neutron is a not positively or negativity charged but both. a neutron is also what makes but the nucleus of an atom.
what is a isotope a isotope is different from a atomic # but is the same as the # of protons
what is a covalent bond a covalent bond is when 2 atoms share an electron they are sharing it and they both get the electron.
what is a ionic bond an ionic bond is when one atom gives one of its electrons away to another atom. the atom that gets the electron will become more negative the other more positive because its giving away one of its electrons.
what is a ion an ion is the total # of electrons in an atom
what is cohesion cohesion is when 2 molecules bond and form a new substance. E.G. water
what is adhesion adhesion is when particles cling to one another
what is dehydration synthesis dehydration synthesis is when a chemical reaction that builds up molecules by water loss.
what is the range of basic pH 8-14
what is the range of neutral pH 7- pure
what is the range of acidic pH 0-6
