Ionic Bonding
Ionic bonding occurs between what two types of particles?
Metal and Nonmetal
Covalent bonds form between what types of elements?
Two nonmetals
Lewis structures show what type of electrons?
Valance electrons
A molecule with 2 atoms total is always this shape.
Linear
Polarity of a bond is determined by differences in what value?
Electronegativity
What happens to electrons in an ionic bond?
Transferring
In a covalent bond, electrons are…
Shared
In a Lewis structure, what do the lines between atoms represent?
Shared pairs of electrons (covalent bonds)
A molecule with 3 atoms total forms this flat, triangle-like shape.
Bent
In the Lewis structure for water (H2O), identify the shared and unshared electrons.
What is a cation?
Positively Charge Ion
A double bond has how many shared electron pairs?
2 Shared Pairs
How many electrons are in a single bond when shown in a Lewis structure?
Two electron
A molecule with 4 atoms total around a central atom, all in a 3D shape.
Tetrahedral
Calculate the best (q) needed to heat 50 grams of water from 10 degrees C to 80 degrees C.
Q = 14,630J
What type of ions often require Roman numerals in names?
Transition Metal Ions
Which type of covalent bond—single, double, or triple—is the strongest, and why?
A triple bond, because it has the most shared electrons
How many electrons make a “full octet” for most atoms in a Lewis structure?
Eight electrons
A molecule with 3 atoms bonded to a central atom and one lone pair forms this shape.
Trigonal pyramidal
Three different solids were dissolved in water, and an electric current was run through each solution. Solid A and C did not conduct electricity, but solid B conducted electricity enough to light up a small light bulb. What can you conclude about the type of bonding present in each solid?
Solid A: Covalent
Solid B: Ionic
Solid C: Covalent
Between NaCl and MgCl₂, which compound has the stronger ionic bond — and what simple reason explains it?
MgCl₂, because Mg²⁺ has a higher charge than Na⁺, so it attracts the chloride ions more strongly
What happens to electrons in a covalent bond that makes it different from an ionic bond?
The electrons are shared instead of transferred
Why do some molecules need double or triple bonds in their Lewis structures?
The atoms don’t reach a full octet with only single bonds
A molecule with 3 atoms bonded to a central atom, no lone pairs, forming a flat triangle.
Trigonal planar
Draw two different Lewis dot structures showing two possible issmomers with the formal C3H6O.
