Periodic Trends Flashcards
What are the characteristics of Group A Elements?
Have an outer electron configuration that is given b the period number and group number. Outer-electron configuration rules are restricted to Group A Elements.
How does Atomic Size change across the Periodic Table?
Atomic size decreases from left to right across a period. It increases from top to bottom in a group/family.
What is Ionization Energy?
The amount of energy required to remove one electron from an atom. Increases across a period from left to right and increases from bottom to top in groups.
What is Electronegativity?
Relative ability of atoms to attract electrons. It increases from the bottom left corner of the Periodic Table to the top right corner of the Periodic Table.
Why are Metals more likely to lose electrons?
They are bigger and have more shells.
Why are Non-metals more likely to gain electrons?
They are smaller.
What happens as Atomic Size decreases?
First ionization energy increases, electrons are harder to remove, and adding more electrons is easier.
What are the characteristics of Group B Elements?
The inner levels are not always completely filled. Do not exhibit consistent periodic trends. Nonrepresentative elements -transition elements -inner transition elements.
What is Electron Affinity?
Energy released when an atom gains an electron. Increases from the bottom left of the table to the top right.
