The Electron Showdown
Which group of elements typically gives electrons away when forming an ionic bond?

What type of charge can an ion have?
Positive or Negative
What is the ionic formula for the bond between sodium (Na) and Chlorine (Cl)?
NaCl
How many valence electrons does Lithium have?
1
What is the octet rule?
Atoms tend to gain or lose electrons to achieve a full outer shell of eight electrons
In the formation of ionic bonds, which type of element tends to take electrons?
Nonmetals
Fill in the Blank: Ionic compounds tend to have __________ melting points.
High
What is the ionic formula for the bond between potassium (K) and Bromine (Br)?
KBr
How many valence electrons are present in a neutral atom of carbon?
4
Which group of elements naturally follows the octet rule without needing to gain or lose electrons?
Noble Gases
Electron giver
Which of the following substances would you expect to be a strong conductor?
Salt water (NaCl dissolved in water)
Dry baking soda (NaHCO3)
Rubbing alcohol (C3H8O)
Salt water
What is the ionic formula for the bond between aluminum (Al) and Oxygen (O)?
Al2O3
Which group of the periodic table contains elements with a full valence shell of electrons?
Noble Gases
How many valence electrons does Neon have, and does it follow the octet rule?
8 valence electrons and yes
3+
Fill in the Blank: In the process of ionic bonding, ions come together because __________ and ___________ ions _____________.
positive, negative, attract
Draw the electron dot structure that correctly represents CaCl2.
Mrs. Eschete will draw the correct structure.
How many valence electrons does Aluminum have?
3
How does the octet rule explain the formation of ionic bonds between sodium and chlorine?
Sodium has 1 valence electrons and gives it away to Chlorine which has 7 valence electrons so both can achieve a full outer shell.
Between the metal and nonmetal in an ionic bond, which one will have greater electron affinity?
When dissolved in water, ionic compounds generally conduct electricity. What is the term for the solution that contains free-moving ions?
Electrolyte
What is the ionic formula for the bond between sulfate (SO2) and calcium (Ca)? (SO2) has a -1 charge
Ca(SO2)2
What group on the periodic table has 2 valence electrons?
Group 2 or alkaline earth metals
