200
the positive subatomic particle and where it is located, the negative subatomic particle and where it is located
What is a proton (in the nucleus) and electron (electron cloud)
200
Bond formed when electrons are transfered between atoms- the atom that gains an electron is a ____ ion and the atom that loses an electron is a _____ ion
What is ionic bond, gains= negative, loses= positive
200
the attraction between water and other water molecules due to its polarity
What is cohesion
300
the scale for neutral substances
What is 7
300
monomer is a nucleotide- not found in food, but already present in your cells
What are nucleic acids?
300
an atom of the same element but with a different number of neutrons
What is an isotope
300
bond formed when a charged hydrogen ion is attracted to an oppositely charged ion in another molecule (polar ends of a molecule attract!)
What is hydrogen bond
300
the measurement of how strong cohesion is- the force that is needed to break the bond between molecules
What is surface tension
400
pure water
What is a neutral substance
400
a macromolecule found in beans and nuts- muscle builder!
What is proteins
400
the mass number
What is number of neutrons plus the number of protons (atomic number)
400
the reason that water is considered a polar molecule
What is the fact that the electrons like to 'hang out' with the oxygen, making the oxygen slightly negative and the hydrogens slightly positive
400
a bug walking on top of water
What is an example of water's cohesiveness and HIGH Surface Tension!
