light elements

• stellar nucleosynthesis - created hydrogen
• subatomic particle is the indicator of the - number of protons
• iron - not considered as light elements
• carbon - formed when three atoms of helium are fused
• stellar nucleosynthesis - process responsible for the formation of elements at the center of star
• neutron capture - nuclear reaction in which a nucleus and one or more neutrons collide to form a heavier nucleus
• oxygen - element formed when carbon is combined with helium
• nuclear fusion - two or more nuclei from a single, heavier nuclei
• neutrino - the process which is responsible for the formation of light elements
• iron - element that is formed at the end of a star's life
• isotope - is a form an element that has the same atomic number of the original element but with different atomic mass
• supernova - explosive death of a star
• nebula - a cloud of interstellar dust
• boyle - greek philosopher who proposes the existence of the atom
• atomos - greek word meaning indivisible
• john dalton - proposed the bowling bowl modek
• jj thomson - proposed the plum pudding model
• nuclear model - proposed by ernest rutherford
• niels bohr - discovered energy level
• erwin schrodinger - developed the electron cloud model
• james chadwick - his theory was neutrons have no electrical charge
• valence electrons - the outermost electrons
• mass number - the sum of the number of protons and neutrons in a particular atom
• 2 atoms of hydrogen and one of oxygen - how do you read h2o in compound
• compound - combination of two or more elements
