Chemistry Basics
Cards in this deck (5)
- 1What is an ion?1: an atom or group of atoms that carries a charge (+ve or
-ve) as a result of having lost or gained one or more electrons
2: a charged subatomic particle (as a free electron) - 2IsotopeTwo or more types of an element with the same atomic number but with
differing atomic mass numbers.
These have nearly identical chemical behavior but different physical properties - 3What does an exergonic reaction do?releases free energy
- 4Name the 5 Halogen Gasesfluorine (F)
chlorine (Cl)
bromine (Br)
iodine (I)
and astatine (At). - 5Valence number of Halogens How reactive and why?Seven valence electrons
VERY reactive
because the outer orbit only requires ONE more electron to become stable
