2.3 Study Guide Flashcards
What happens in a covalent bond?
Two non-metals join together to make a bond.
What happens in a polar covalent bond?
Two non-metals join together to make a bond, however, the non-metals are slightly attracted to each other.
What happens in an Ionic bond?
A non-metal and a metal join together to create a bond. In the bond the atoms are attracted to each other.
What is the difference between a polar and non-polar bond.
In non-polar bonds, the electrons are shared equally, whereas, in polar bonds, the non-metals are shared unequally.
What is the easy way to determine electronegativity?
The further the element is to the right of the periodic table, the stronger the electronegativity. However, the element furthest vertically has the stronger electronegativity. Rows vertically outweigh columns horizontally.
What type of bond will form between Na(Sodium) and O(Oxygen)?
An Ionic bond is formed between the two elements.
What type of bond will form between F(Fluorine) and N(Nitrogen)?
A covalent bond will be formed between the two elements.
What type of bond will form between K(Potassium) and Cl(Chlorine)?
An Ionic bond will form between the two elements.
How does electronegativity affect the type of bond two atoms will form?
If the difference in electronegativity between two atoms is widely different, then the bond will be polar, if the electronegativity is very similar then the bond will be non-polar.
