Elements and Compounds
How the periodic table is organized
What are periods and groups
The electrons in an atom with the most energy
What is valence electrons
What holds ionic compounds together
Force that holds two or more atoms together in a compound
What is chemical bond
An atom that is no longer electrically neutral because it has lost or gained electrons
What is an ion
Properties of covalent compound
What is low boiling points and melting points
The reason atoms gain, lose, or share electrons
What is to become chemically stable
How to metals bond with one another
What is electron pooling
Outermost electron of an atom that participates in chemical bonding
What is valence electron
A molecule that has a partial positive end and a partial negative end because of unequal sharing of electrons
What is polar molecule
Is salt polar or nonpolar and why?
What is polar and polar compounds dissolve in other polar compounds
Why does an atom that gains an electron now have a negative charge?
What is there are now more electrons than protons
What is the elements and how many atoms of the elements in a compound
A model that represents valance electrons in an atom as dots around the element's chemical symbol
A group of chemical symbols and numbers that represents the elements and the number of atoms of each element that make up a compound
What is chemical formula
Why is water a polar compound?
What is hydrogen has a partial positive charge and oxygen has a partial negative charge
What is -2
How many pairs of electrons does the element on the board have
What is 3
A bond formed when many metal atoms share their pooled valance electrons
What is metallic bond
A group of atoms held together by covalent bonding that acts as an independent unit
What is a molecule
Where are metals, nonmetals, and metalloids on the periodic table
Can neon easily form a chemical bond? Why or why not?
What is no, its energy level is full
How many valance electrons does Oxygen have?
What is 6
The attraction between positively and negatively charged ions in an ionic compound
What is Ionic Bond
A chemical bond formed when two atoms share one or more pairs of valence electrons
What is covalent bond
