p-block
100
What type of bond does Li and S have?
Polar covalent
100
what is molecular geometry?
is the 3D arrangement of the atoms that make up a molecule.
200
What is Atomic Radius
The distance between the center of the nucleus of an atom and the outermost electron.
200
What is the oxidation number for Nitrogen?
-3
200
What differences are between metals and non-metals?
Metals are conductors of heat, have electric current, are solid at room temperature, and can rust. Non-metals are poor conductors of heat, have no electric current, may not be solid at room temperature, and may not rust.

300
What type of ond is Mg and N?
covalent polar
300
what does polarity determine?
how equally bonded electrons are shared between atoms and the separation of electric charge.

500
Which has a lower ionization energy: Iridium or Nickel?
Iridium
