Front (Question)

What is the electron-pair repulsion theory?

Back (Answer)

1) electron pairs repel so they are arranges as far as possible 2) arrangement of electron pairs minimises repulsion and holds bonded atoms in shape

Front (Question)

Is a lone pair of electrons closer or further to the central atom, than a bonded pair?

Back (Answer)

closer

Front (Question)

Does a lone pair of electrons repel more strongly or less strongly than a bonded pair?

Back (Answer)

Front (Question)

What is the relative repulsions between lone pairs and bonding pairs?

Back (Answer)

bonded-pair/bonded-pair < bonded-pair/bonded-pair < lone-pair/lone-pair

Front (Question)

What is the name of the shape with 4 bonded pairs and 0 lone pairs?

Back (Answer)

tetrahedral

Front (Question)

What is the name of the shape with 3 bonded pairs and 1 lone pair?

Back (Answer)

pyramidal

Front (Question)

What is the name of the shape with 2 bonded pairs and 2 lone pairs?

#17

Front (Question)

Why does electronegativity change when the bonded atoms are different elements?

Back (Answer)

1) nuclear charges are different 2) atoms may be different sizes 3) shared pair of electrons may be close to one nucleus

#18

Front (Question)

What is electronegativity?

Back (Answer)

the attraction of a bonded atom for the pair of electrons in a covalent bond
