Chemistry Flashcards
The rows in the periodic table are called?
A Period
a group of elements with similar properties is called?
A Family
Name all the families of the Periodic Table
Alkali Metals, Alkaline Earth Metals, Halogens, Noble Gases
Where are Metals and Non Metals found on the Periodic Table?
Metals are found on the left side of the staircase while Nonmetals are found on the right side of the staircase
What are atoms?
atoms are the building blocks of life
What do atoms consist of?
Atoms consist of protons, neutrons, electrons
What is an ion?
An ion is a particle that has a positive or negative charge
What is the valence charge?
valence charge is tha ammount of atoms an ion loses or gains to become stable
What does the Ion symbol represent?
the amount of atoms an ion has lost or gain
What are Cations?
Cations are positively charged metal ions that has lost electrons
What are Anions?
Anions are negatively charged non-metal ions that have gained electrons
what are electron dot diagrams
electron dot diagrams are diagrams that show the number of valennce electrons and concentrate on the outermost shell of the atom.
What are compounds composed of?
compounds are composed two or more types of atoms chemically bonded together in a fixed proportion
What are ionic compounds composed of?
Ionic compounds are composed of a metal and non metal, OR a metal and polyatomic ion
What are covalent compundes made of?
Covalent compounds are made up of two nonmetals
What is a chemical reaction?
a chemical reaction is a change in matter that produces new substances with new properties.
Give signs of a chemical change
New odor, light or heat is produced, bubbles formed, and unexpected color change.
State the Law of Conservation of Mass
the total mass of the products is equal to the total mass of reactants.
What is HOFBrINCL?
elements that are not strong enough to stand alone, becoming diatomic ions. (add 2)
What is a Synthesis Reaction
two or more reactants combine to produce one new product
What is a Decomposition reaction?
When one compound breaks down into two or momre simpler compounds
What is a Single Displacement Reaction
One free element replaaces another element in a compound
What is a Double Displacement Reaction
the metal ions of two different inonic compounds exchange places
When naming Monovalent Binary Ionic compounds..
The first element(metal) keeps its name
The second element(non-metal) has its name modifies to end in “ide”
