Basics of atomic structure and the periodic table
| Question | Answer |
|---|---|
| Two subatomic particles found in the nucleus | protons and neutrons |
| Subatomic particles with a positive charge | protons |
| Subatomic particle(s)identified by the atomic number for a neutral atom | proton or electrons |
| Subatomic particles with a negative charge | electrons |
| Decimal number in the periodic table square | atomic mass |
| Visually shows the number of valence electrons as dots around the chemical symbol of an element | Lewis Dot diagram(s) |
| whole number in the periodic table square | atomic number |
| building blocks of elements | atom |
| found inside the nucleus, have a positve charge, and a mass of 1 amu | protons |
| Used to identify the number of energy levels for an atom | period |
| type of matter composed of only one type of atom | element |
| type of matter where two or more elements are chemically bonded together | compound |
| only metal touching the metalloid staircase | aluminum |
| Elements in group 2 | alkaline earth metals |
| Elements with similar chemical properties are found in the same.... | group |
| only metal in liquid state at room temperature | mercury |
| maximum number of electrons held by the second energy level | eight |
| an atom with a change in electrons but constant proton count | ion |
| an atom with the same proton count but a change in mass due to a change in neutron count | isotope |
| Elements in group 17 | halogens |
| subatomic particle count found by subtracting the mass number and atomic number | neutrons |
| Elements in the detached rows at the bottom of the periodic table | rare earth or inner transition metals |
| electrons found in the last or outermost energy level | valence electrons |
| The dots in a Lewis Dot diagram | valence electrons |
| atomic number represents this particle in a NEUTRAL atom | electrons |
| small, dense core of the atom | nucleus |
| Elements in group 18 | noble gases |
| Maximum number of electrons found in the third energy level | eighteen |
| Maximum number of electrons found in the fourth energy level | thirty-two |
| only non-metal on the left side of the periodic table; may have either a +/-1 charge | hydrogen |
| special name for any particle found in the nucleus | nucleons |
| subatomic particles with a mass of 1 amu and no charge | neutrons |
| rounded version of the atomic mass;sum of protons and neutrons for one isotope | mass number |
| Maximum number of electrons in the energy level closest to the nucleus | two |
| Elements in Group 1; except hydrogen | Alkali metals |
| Chemically inert or unreactive elements because they have a complete valence shell | noble gases |
| elements found in groups 3 through 12 | transition metals |
| smallest form of matter | atom |
| Most active non-metal element | fluorine |
| Most active metal element | cesium |
| only non-metal liquid at room temperature | bromine |
| Subatomic particle with a negative charge and essentially no mass | electron |
| vertical columns of the periodic table | groups or families |
| horizontal rows of the periodic table | periods |
| Identifies the valence electron count for an element except the transition metals | group number |
