What does it mean if an atom is more electro negative than another. | It means it is better at attracting electrons. |
The definition of electro negativity. | Electronegativity is the power of an atom to attract the electron density in a covalent bond towards itself. |
What is electron density? | It's the term used to describe the way the negative charge is distributed in a molecule. |
What is the Pauling scale. | Is the scale used as a measure of electronegativity. |
What does electronegativity depend on? | Nuclear charge, the distance between the nucleus and the outer shell electrons, the shielding of the nuclear charge by electrons in inner shells. |
As we go up a group in the periodic table, what happens to electro negativity. | It increases. The atoms get smaller. There is less shielding by electrons in inner shells. |
As we go across a period what happens to the electro negativity? | It increases. |
What is the polarity of covalent. | Polarity is about the unequal sharing of the electrons between atoms that are bonded together covalently. |
