2.3 Flashcards
What are the components of the nucleus of an atom
Protons and neutrons
What is the charge of the nucleus of an atom
Positive
The ability for an atom to ATTRACT electrons
Electronegativity
Covalent bonds
SHARE electrons
2 non-metals
Covalent bonds
An atom with 7 valance electrons will
Gain 1 electron
Gain electrons
Non metals
N2O5 and CO2
Covalent
Non-polar covalent bonds share electrons
Equally
Between 2 identical non-metals
Polar covalent bonds share electrons
Unequally
Between any 2 different non-metals (except C - H and S - H
F - H
Polar covalent bond
N - O
Polar covalent bond
The ability of an atom to attract electrons from another atom while in a compound
(desire for an atom to gain electrons)
Electronegativity
The separation of electric charge
Due to the shifting of electrons
Polarity
Unevenly matched game of tug of war where one side pulls harder
Polar bond
Evenly matched game of tug of war where both sides pull equally on rope
Non polar bond
Non metal atom with high electronegativity shares electrons with a non metal atom with low electronegativity
Polar Covalent bond
An atom of Mg and an atom of O would form what bond?
Ionic
Atom with high electronegativity shares electrons with an atom with equally high electronegativity
Non polar covalent
2 Fl atoms share electrons to form a bond
Non polar covalent
