What particles are located in the center Protons and Neutrons of an atom? What do the number of protons They determine the atomic number. determine? Neutral atoms have _________ protons equals amounts of and electrons. Positive ions have _________ protons more than electrons. Negative Ions have _________ protons less than electrons. What is another name for a positively Cation charged atom? What is another name for a negatively Anion charged atom? protons > electrons Positively Charged Atom (Cation) electrons < protons Negatively Charged Atom (Anion) protons = electrons Neutrally Charged Atom Top Number = ? Bottom Number = ? Letter = ? Element Symbol Charge Atomic Number An abbreviation of the element. Protons plus the number of neutrons determine whether or not an atom is positively or negatively charged. The number of protons in an atom. Protons + Neutrons Mass Number The mass number is the amount of subatomic particles that reside in the nucleus of an atom. Hyphen Notation The element name - mass number. What particles affect the stability of an Protons and Neutrons atom? What particles DON'T affect the Electrons stability of an atom? Oxygen-16 What are the stable forms of oxygen? Oxygen-17 Oxygen-18 What is an isotope? When atoms are the same element, but have different amounts of neutrons that reside in their nuclei. What are two requirements for an ∙ Different numbers of neutrons atoms to be isotopes of each other? ∙ Same elements What happens to the mass numbers The mass number changes due to the different number of neutrons in each between atoms when they are isotopes of them. of each other?
