Chemistry Alphonse HS Test Family/Group Names and Electron Configuration

low melting and boiling points, brittle, not good conductors

nonmetals

high melting and boiling points, malleable, conduct electricity and heat well

metals

elements that have properties in between metals and nonmetals

metalloids

react violently with water

alkali metals, alkaline earth metals

3 alkali metals

Li, Na, K

3 alkaline earth metals

Be, Ca, Mg

3 transition metals

Fe, Cu, Au

3 post transition metals

Al, Sn, Pb

3 metalloids

As, Bi, Si

3 halogens

F, Cl, Br

3 noble gasses

He, Ne, Ar

why are copper and aluminum used for wires

conduct electricity well as transition metals

why are rubber and nonmetals used for oven mitts to remove hot things

they transfer heat slow to prevent a burn

4 building block elements of life

C, H, O, N

how many electron in s orbital

2

how many electron in p orbital

6

how many electron in d orbital

10

as principal quantum number increases, how does size and energy change

orbital is larger and increases in energy

aufbau principle

electron occupies lowest energy orbital first

pauli exclusion principle

maximum of 2 electrons occupy a single orbital, only if the electrons have opposite spins

what is an orbital diagram

orbital diagram uses boxes to show electron spin and orbital occupation

hunds rule

single electrons with the same spin must occupy each equal energy orbital before electrons of opposite spins can occupy the same orbitals
