i can explain the properties of the main groups on the periodic table (noble gases, halogens, transition metals, alkaline earth metals, and the alkali metals)
3a match the following terms with their descriptions. (2 points)
group
noble gases
alkali metals
alkaline earth metals
transition metals
halogens
organizes elements with similar properties together where each element has the same number of valence electrons.
very reactive nonmetals and gases. want to gain 1 valence electron to complete their octet
somewhat reactive metals, all want to lose 2 valence electrons
extremely reactive metals that react in water or air due to wanting to lose 1 valence electron.
all elements in this group have full outer energy levels/complete outer shell of electrons
elements in groups 3 - 12 on the periodic table. contains a wide range of metals

Explanation:

Noble gases have full outer - energy levels. Alkali metals are extremely reactive metals that want to lose 1 valence electron. Alkaline earth metals are somewhat reactive and want to lose 2 valence electrons. Transition metals are in groups 3 - 12 and have a wide range of properties. Halogens are very reactive non - metals that want to gain 1 valence electron. A group organizes elements with similar properties and same number of valence electrons.

Answer:

Group: Organizes elements with similar properties together where each element has the same number of valence electrons.
Noble Gases: All elements in this group have full outer energy levels/complete outer shell of electrons.
Alkali Metals: Extremely reactive metals that react in water or air due to wanting to lose 1 valence electron.
Alkaline Earth Metals: Somewhat reactive metals, all want to lose 2 valence electrons.
Transition Metals: Elements in groups 3 - 12 on the periodic table. Contains a wide range of metals.
Halogens: Very reactive nonmetals and gases. Want to gain 1 valence electron to complete their octet.
