Chemical Bonds Flashcards
the smallest component of an element that retains all of the chemical properties of the element.
atom
at the most basic level all organisms are made of a combination of elements that contain atoms that combine together to form
molecule
all atoms contains
- protons (positive charged)
- electrons (negatively charged)
- neutrons (no charge)
balance each other in a neutral atom , which has a net zero charge
protons and electrons
How elements interact with one another depends on how their electrons are arranged and how many openings for electrons exist at the outermost region.
chemical bonds
Electrons exist at energy levels that form shells around the nucleus.
chemical bonds
how many electrons does the closest shell can hold
2 electrons
it can hold up to 8 electrons
2nd and third energy levels
states that atoms gain, lose or share electrons to fill their outermost energy shell with 8 valence electrons
