2.3 Flashcards
What happens to electrons during an IONIC Bond?
They are transferred and the atom with higher electronegativity gains one.
What happens to electrons during a COVALENT Bond?
They are shared between 2 atoms.
What happens to electrons during a POLAR COVALENT Bond?
They are shared between 2 atoms unequally.
What happens to electrons during a NON-POLAR COVALENT Bond?
They are shared between 2 atoms equally.
What are the properties of an Ionic Bond?
— Non Metal + Metal
— Are held together due to opposite charges
— High Melting Points
— Soluble in water
— Only between 1 atom with high EN and one with low EN
What are the properties of a Covalent Bond?
— Non Metal + Non Metal
— Are held together by sharing electrons
— Only between 2 atoms with high EN
What is the difference between a Polar and Non-Polar Covalent Bond?
Polar do not share electrons equally, while Non-Polar do.
What type of bond will form between K and Cl? Why?
Ionic. This is because 1 is metal and 1 is non-metal, so one has a high EN and one has a low EN.
What type of bond will form between C and Cl? Why?
Polar Covalent. They are both non-metals and have high EN, but Cl has a higher EN so it will have more pull than C.
What type of bond will form between Cl and Cl? Why?
Non-Polar Covalent. They both are non-metals and have high EN, and they’re EN is the same because they are the same element.
