Atoms, Bonding, and the Periodic Table
Between atoms, chemical bonds form when electrons do this.
What is transferred/shared?
The name of this NH4+ polyatomic ion, used in glass cleaners.
What is ammonium?
Bonds that form between two non-metals.
What is a covalent bond?
Made by melting and mixing metals together in measured amounts
What are alloys?
The melting point of an ionic compound (in order for the bond to break)
What is high melting point?
The number of valence electron a neutral atom never has more than.
What is eight electrons?
The total charge of an ionic compound.
What is zero/neutral/no charge?
The total number of electron shared in a double covalent bond.
What is 4/ 2 pairs of?
Metal crystal consist of positively charged metal ions embedded in a freely moving "sea" of
What is electrons?
What is polar?
In the periodic table, atoms are arranged from left to right and from top to bottom in this order.
What is increasing atomic number/electrons?
To from ions, the element in group 1 do this.
What is lose one electron?
Molecular compounds that dissolve in water do not conduct electricity because of this reason.
What is no charged particles/ions?
Solid metals are good conductors of heat and this.
What is electricity?
The name of this polyatomic ion NO3-
What is nitrate?
The group that do not usually react with other elements because it has 8 valence electrons with the exception of helium.
What is Group 18/noble gases?
The total number of positive charges and the total number of negative charges must be equal to from this.
What is an ionic compound?
The name of a compound that consists of molecules made of atoms that are covalently bonded.
What is a molecular compound?
The name of the alloy with this mixture:
iron, carbon, nickel and other elements.
What is steel?
The number of electron that group 16 is willing to gain?
What is two?

What is Group 17 / halogens?
Ionic compound does this in water.
What is dissolve/ionize/move freely?
When valence electrons are shared equally between 2 atoms. ie.. F2 (Flourine)
What is a nonpolar molecule?
Something that every alloy has.
What is at least one metal component?
The total number of electrons shared in a triple covalent bond.
