Question | Answer |
---|---|
the ability to attract electrons from nearby atoms | electronegativity |
this number tells you the number of valence electrons | group number |
ions that have a positive charge + lose valence electrons | cation |
groups that are anions | 5A, 6A, 7A |
what is the rule about d block electron configurations | period minus 1 |
said that electrons are placed in the lowest energy level first (s) | Aufbau |
ions that have a negative charge + gain valence electrons | anions |
groups that are cations | 1A, 2A, 3A |
said that electrons will have the same spin until each orbital has 1 electron | Hund |
element that is stable with only 2 valence electrons | He |
a visual representation of only the valence electrons | Lewis Dot structure |
element where the 3 electron configurations stop working | V |
element(s) that are the first exceptions to the electron configuration rules | Cr and Cu |
said that electrons will have opposite spins when in the same orbital ; 2 is the max # | Pauli |
a visual representation of ALL the electrons an element has | electron configuration |
only group with a full number of valence electrons | 8A |
element with the most electronegativity and ionization energy | F |
element with the largest atomic mass | Fr |
the energy needed to remove electrons from an atom | ionization |
innermost electrons; lower energy | core |
outermost electrons; highest energy | valence |
measure of the diameter between the nuclei of 2 atoms of the same element | atomic size |
block with a max number of 2 valence electrons | s |
block with max number of 14 valence electrons | f |
block with max number of 10 valence electrons | d |
block with max number of 6 valence electrons | p |
