Chapter 6 Flashcards
What is the definition of noble gas
The s and p levels are completely filled with electrons
What are the symbol colors?
Black: Solid at room temp
Red: Gas at room temp
Blue: Liquid at room temp
What is the definition of Representative Elements
The s and p sublevels in the highest occupied energy level are not filled
What is atomic size
Distance between the nuclei of two joined atoms of the same element
What is atomic radius?
One half the distance between nuclei
What is nuclear charge?
The strength of the charge of the nucleus that pulls electrons in
What is electron shielding
Electrons closer to the nucleus block the charge from pulling in electrons that are further away. Stronger than nuclear charge
What is an ion?
An atom with a positive or negative charge from taking away or adding an electron
Do nonmetals form cations or anions?
Anions by gaining electrons to become negative
What is ionization energy?
The energy required to remove an electron from an atom
What size are cations and anions in relation to the original atom?
Cations: smaller
Anions: bigger
What is Electronegativity
The ability of an atom of an element to attract electrons when the atom is in a compound
What is the largest level of Electronegativity? Smallest?
Largest: .4
Smallest: .7
