Chemistry Flashcards
What is the periodic table ordered by
Atomic number and electron arrangements
Group 1
Alkali metals
Area between Group 2 & 3
Transition metals
Group 7
Haolgens
Group 8
Noble gasses
Very recative metals
Alkali metals
Very reactive non-metals
Halogens
Very un reactive non metals
Noble gasses
What type of particle is every element made of
Atoms
3 types of particles
Protons, eutrons and electrons
Why neutrons neutral
The protons and neutrons will cancel each other out
Mass of proton
1 mass unit
Mass of neutron
1 mass unit
Mass of eletron
1/2000 negligible
Isotopes
They are more than one form of the same element with the same number of protons and different number of neutrons
Nucleotide notation
Is the sign of an element with the mass number on the top and the atomic number at the bottom
Covalent bonding
The attraction of the opposite nuclei for the shred pair of electrons. Only non metals
One bond
Linear
Two bonds
Angular
3 bonds
Trigonal pyramidal
4 bonds
Tetrahedral
