Module 6 Lesson 1 Flashcards
Structure of Atom
Protons and Neutrons in center
Electrons orbit around center
Atoms have same number of Protons as Electrons
Periods
Horizontal Rows, in order of atomic number
Groups
Vertical columns, in order of amount of valence electrons
Atomic Number
Same as the amount of protons and electrons
Ionic bond
Atom will donate or obtain an atom to create a full outermost shell. This gives this atom a slight attraction which causes an
electrical attraction between two oppositely charged atoms or groups of atoms.
Covalent Bond
Bond formed by two different atoms sharing electrons instead of giving them up or taking them from other atoms. Makes both atoms happy
Atom
building block of matter; contains subatomic particles— neutrons, protons, and electrons.
Nucleus
center of an atom; contains neutrons and protons. In eukaryotic cells, the central membrane-bound organelle that manages cellular functions and contains DNA.

Proton
tiny atomic particle that has mass and a positive electric charge.
Nuetron
particle without a charge in an atom’s nucleus.
Electron
tiny atomic particle with little mass and a negative electric charge; an atom’s electrons are equal in number to its protons and are located in a cloud like region surrounding the nucleus.
Element
natural or artificial substance that cannot be broken down into simpler substances by physical or chemical means.
Compound
substance composed of atoms of two or more different elements that are chemically combined.
Ion
atom that is negatively or positively charged because it has lost or gained one or more electrons.
