Properties of metals

A

malleable (can be hammered into a thin sheet), ductile (can be drawn into a thin wire), lustrous (shiny, reflective), and they conduct Electricity and heat.

17
Q

Orbitals are categorized as

A

s (lowest energy), p, d, or f-type(highest energy)

18
Q

Different atoms react the same when

A

They have the same number of electrons in the same type of orbital on the atom surface.

19
Q

How many orbitals are on each sub-shell? (S,p,d,f)

A

The s subshell contains 1 orbital, the p subshell contains 3 orbitals, d contains 5 orbitals, and f contains 7 orbitals.

20
Q

Each orbital can contain

A

2 electrons per orbital
(ie s(1) can hold 2 electrons, p(3) can hold 6…)

21
Q

the radius of an atom __ as we go down within a group on the periodic table

A

increases

22
Q

the atomic radius tends to __ as we move across a row in the periodic table

A

decrease

23
Q

ionization energy of an atom

A

The energy required to remove an electron from an atom

24
Q

electron affinity

A

The energy released when an atom gains an electron

25
Q

Ionization energy and electron affinity tend to

A

increase going across a row in the periodic table and to decrease going down a column.
