Periodic Table
This is the man we credit with the modern periodic table.
Who is Mendeleev?
This subatomic particle is responsible for determining the identity of the atom.
What is the proton?
This is how you determine whether a compound is ionic or molecular.
What is look at the elements present, an ionic compound has a metal or NH4+ ?
This subatomic particle is responsible for determining the identity of the isotope of an atom.
What is the neutron?
This type of element is lustrous, conductive, reacts with acid, and malleable.
What is a metal?
In a chemical reaction, these are the substances on the left side of the arrow.
What are reactants?
This is the name of the rows of the periodic table and how they are organized.
What are periods and by increasing atomic number?
This subatomic particle is responsible for determining the reactivity of the atom.
What is the electron?
This is the name of MgI2
What is magnesium iodide?
True or false: Isotopes have the same chemical properties just with different masses.
What is true?
Air is an example of this.
What is a mixture?
This is the definition of the law of conservation of matter.
What is that matter cannot be created or destroyed?
This is the name of the columns in the periodic table and how they are organized.
What are groups (or families) and by similar physical and chemical properties?
These are the three subatomic parts of the atom and their charges.
What are positive protons, neutral neutrons, and negative electrons?
This is the formula of dicarbon hexahydride.
What is C2H6?
This is the isotope name for the isotope with 12 protons and 13 neutrons.

Elemental nickel is white to light grey in color, highly ductile, lustrous, and resistant to tarnish. Pt is likely to share the properties. This is the explanation.
What is because they are in the same family?
The name and charge of an atom or group of neutral atoms that have gained electrons.
What are anions and negatively charged?
This is when you need to use roman numerals in naming ionic compounds.
What is when the metal ion forms more than one possible charge?
This is how you determine the mass number in an atom.
What is #p+ + #n0 ?
This type of element is brittle, conductive, and lustrous.
What is a metalloid?
