Atoms
Alkali Metals, Alkaline Earth Metals, and Transition Metals
What are the three types of metals?
The amount of this subatomic particle can be different for the same element.
What is a neutron?
This is the formula for Lithium Chloride.
What is LiCl?
These types of elements can take on properties of both metals and nonmetals.
What are metalloids?
This is a region of an atom where electrons orbit the nucleus.
What is the electron cloud?
This is a column on the periodic table.
What is a group?
This is an average of the mass of all isotopes of an element.
What is atomic mass?
This is the formula for Magnesium Phosphide.
What is Mg3P2?
This type of metal is highly reactive.
What is an alkali metal?
This subatomic particle does not carry a charge.
These elements are stable by themselves and are not reactive.
What are Noble Gases?
8537Rb
What is Rubidium-85?
This is the formula for Tin (IV) Sulfide.
What is SnS2?
NaCl is considered this type of compound.
What is a binary ionic compound?
This amount of this subatomic particle defines the identity of the atom.
What is a proton?
This is the number of electrons in the outermost shell of an atom.
What are valence electrons?
This element has a mass of 183.84 amu.
What is W (Tungsten)?
This is the formula for Manganese (II) Chlorate.
What is Mg(ClO3)2?
CO is considered this type of compound.
What is a molecular compound?
This model of the atom was not widely accepted because it did not follow the scientific method.
This periodic trend decreases going across the periodic table from left to right because the number of valence electrons increases along with the number of protons, pulling the electrons inward.
What is atomic radius?
These elements have masses of 102.905 and 83.80 amu.
This is the formula for Ammonium Sulfate.
What is (NH4)2SO4?
This family of elements carries a -1 charge due to their number of valence electrons.
What are halogens?
