Video Questions
What is a polar covalent bond?
How are polar covalent bonds formed.
How is polarity measured?
Some text here about the topic of discussion
3
Polarity (-ve or +ve poles) depend on the electronegativity values on Table S
Some text here about the topic of discussion
4
Electronegativity indicates how strongly an atom of an element attracts electrons in a chemical bond.
Electronegativity values are assigned on Table S
5
Oxygen is very electronegative so it pulls electrons to itself
Some text here about the topic of discussion.
Water is a Polar Molecule
6
The general Rule for polarity is
Metals -low electronegativity numbers
Non-metals - high electronegaticity value
Some text here about the topic of discussion
