Front (Question)

Metalic bond

Back (Answer)

Attraction between positive metal ions and delocalised electrons

Front (Question)

Ionic bond

Back (Answer)

Electrostatic attraction between oppositely charged ions

Front (Question)

Which elements do not form ions?

Back (Answer)

Boron Carbon (usually) Silicon (usually)

Front (Question)

What ions does tin form?

Back (Answer)

Sn⁴⁺ (most stable) and Sn²⁺

Front (Question)

What ions does lead form?

Back (Answer)

Mostly Pb²⁺ but some Pb⁴⁺

Front (Question)

Covalent bond

Back (Answer)

A shared pair of electrons

Front (Question)

What is a lone pair?

Back (Answer)

A pair of electrons which are not bonded

Front (Question)

What are non-octet molecules?

Back (Answer)

Molecules where the central atom does not have a noble gas electron arrangement

Front (Question)

Coordinate bond

Back (Answer)

A covalent bond in which both electrons of the shared pair come from the same atom

#10

Front (Question)

How does a lone pair effect the bond angle?

Back (Answer)

Reduces angle by 2.5 degrees

#11

Front (Question)

Electronegativity

Back (Answer)

The power of an atom to attract the pair of electrons in a covalent bond

#12

Front (Question)

Most electronegative atom

Back (Answer)

Fluorine

#13

Front (Question)

Why does electronegativity increase across a period?

Back (Answer)

The number of protons (nuclear charge) increases

#14

Front (Question)

Why does electronegativity decrease down a group?

Back (Answer)

Atomic radius increases as the number of shells increases

#15

Front (Question)

Why don’t the noble gasses have electronegativity values?

Back (Answer)

They do not usually form covalent bonds

#16

Front (Question)

Three types of intermolecular force

Back (Answer)

• van der Waals’s forces • Permanent dipole-dipole forces • Hydrogen bonds

#17

Front (Question)

Electron deficient

Back (Answer)

Where the central atom of a non-octet molecule has fewer electrons than the noble gas configuration

#18

Front (Question)

Expanded octet

Back (Answer)

Where the central atom of a non-octet molecule has more electrons than the noble gas configuration
