Module 2 Flashcards
Atoms
A+B -> AB
Synthesis
AB -> A+B
Decomposition
AB+CD -> AC+BD
Exchange Reaction
Polar Covalent
a bond in which electrons are not shared equally
Ionic bond
a bond in which electrons are lost or gained forever
Non-polar covalent
a bond in which electrons are shared equally
Hydrogen bonds
a bond formed not by chemical reactions, but associations
The electron orbital or shell which will determine an atom’s chemical reactivity is known as the…
Valence orbital
The term describing the loss of energy in a chemical reaction is…
Exergonic
Ionic bonds form between two atoms when…
one atom donates an electron to another atom forever
what is the atomic theory of matter
matter is the “stuff” we are made of, elements are made up of like atoms or isotopes of these atoms
what are atoms
nucleus (protons +neutrons) + electron orbitals
what is the atomic number
the # of protons which is equal to the # of electrons
what is the atomic mass
the # of neutrons +the # of protons = mass number
how do you determine the electron configuration of an element
each electron shell can hold an optimum number of paired electrons and must fill up from closest to furthest
