What are elements in group 17 or 7A period 2-5 referred to as?
Halogens (non-metals)
39
Halogens contain _____ atom/s joined together.
Two!
40

Elements containing properties of both metals and non metals.
44
What 3 subcategories follow metals on the periodic table?
Alkali metals, alkaline earth metals, and metalloids.
45
When moving down a group on the periodic table, the atomic size and ionization energy _____.
Increases
46
The size of an atom _____ when moving across (left to right) a period as more electrons are _____.
Decreases, added.
47
The more _____ the smaller the _____.
Electrons, atom.
48
What is a cation?
A positively charged ion.
49
What is an anion?
A negatively charged ion
50
Relative amu of an electron?
~0.0005
51
Relative amu of a proton?
~1
52
Relative amu of a neutron?

An _____ has the same number of protons and _____ but a different number of _____.
Isotope, electrons, neutrons.
54
An _____ has the same number of protons and can have different numbers of _____ and _____.
Element, electrons and neutrons.
55
How do you determine atomic mass?
