Covalent
What element types are used when forming a covalent bond?
Nonmetals & Nonmetals
What are the characteristics of an ionic bond?
Ionic bonds have low electronegativity values, (one weak metal electron, one strong nonmetal electron) the element is brittle and can conduct as a liquid but not a solid.
What are the electrons like in a metallic compound/element?
They are tightly packed
Write the formula for Aluminum and Bromine.
AlBr3
Where on the periodic table are covalent elements located?
On the right side of the periodic table (in the P group)
What elements form ionic bonds?
Nonmetals & Metals
What elements make up metallic bonds?
Metals and metals
What type of bond is Technetium (Tc) and Titanium (Ti)?
Metallic- they are two metals
What is the structure of a solid for a covalent element?
Covalent elements can form individual molecules or large networks of atoms all bonded together.
In what state of matter allows Ionic compounds to conduct electricity?
Liquid
Why are metallic elements good conductors of electricity?
Write the formula for the compound:
H and PO4
Sn3(PO4)4
Distinguish the key details that make covalent bonds covalent.
In covalent bonds, there are large electronegativity charges, they cannot conduct, are composed of nonmetals, and tightly share electrons.
Predict what would happen if ionic elements could also conduct as a solid. Would they still be considered ionic? Why?
They would no longer be considered ionic elements and instead metallic elements because metallic elements always conduct as a solid.
How does the element being malleable affect the conductivity of a metallic element?
There isn't a direct relationship between the two. When the electrons are moving that's what is causing the electricity to be able to conduct.
What bond does Germanium (Ge) and Arsenic (As) have?
Ionic- a nonmetal and a metal
Imagine what would happen if covalent bonds had a higher electronegativity. Would they still be considered covalent?
They would be considered metals. Electronegativity increases going left to right.
Evaluate how the strength of an ionic bond would change if the ions were smaller.
The force of attraction would increase
Predict what the elections look like in a metallic element/compound. How does this help us determine if it is a metallic bond or not?
They are loosely shared to be able to conduct electricity as a solid. This helps us to know that the element or compound is metallic because metallic bonds always conduct as a solid.
What bond does the formula below have and write the name?
Cl2O7
- covalent bonded
- Dichlorine heptoxide
