C3 Atomic Structure and the Periodic table

Question 1

Atomic number

Answer 1

Number of Protons

Question 2

Atomic Mass

Answer 2

Number of Protons and Neutrons

Question 3

What is an Isotope

Answer 3

Two atoms with the same number of protons but a different number of neutrons are said to be isotopes.

Question 4

4 Features of Isotopes

1. form of elements with a _____________
2. same number of _____________
3. forms of elements with a_____________
4. same _______

Answer 4

-form of elements with a different number of neutrons
-Same number of electrons in their outer shell
-forms of elements with the same number of protons
-same properties

Question 5

what is an Ion?

Answer 5

Charged Ions (either positive or negative.)

Question 6

Ionic bond are
atoms_____ ______ its electrons to be ______.
It forms between _____ and _____-_______

Answer 6

Atom giving away its electrons to be stable.
-forms between metals and non-metals

Question 7

Covalent bond

Answer 7

2 atoms sharing pairs of electrons to be stable.
-forms between non-metals

Question 8

metals _____ electrons to be _____
non-metals _____ Electrons to be _____

Answer 8

metals lose electrons to be positive
non-metals gain electrons to be negative

Question 9

ionic compounds are hold together by a strong _________ force of _______ between _______ charged ____

Answer 9

ionic compounds are hold together by a strong electrostatic force of attraction between oppositely charged ions

Question 10

ionic bonding
(structure, how it is held together, melting point, conductivity)

Answer 10

has a giant lattice structure

held together with electrostatic force of attraction

has a high melting point: requires a lot of energy to weaken the force of attraction

only conducts when molten(melt) or aqueous (dissolved): ions are fixed in solid but can move when aqueous or molten

Question 11

simple covalent bonding
(structure, how it is held together, melting point, conductivity)

Answer 11

has a small molecule structure

atoms are held together by strong covalent bonding. Molecules are held by weak intermolecular forces

has a low melting point: weak intermolecular forces of attraction

doesn’t conduct electricity because there are no mobile charge carriers

Question 12

giant covalent bonding
(structure, how it is held together, melting point, conductivity)

Answer 12

has Giant (lots of) covalent bonds

has high melting point because lots of covalent bonds require a lot of energy to break

it doesn’t conduct electricity because no mobile charge carriers (except graphite which has delocalised electrons)

Question 13

Metallic bonding
(structure, how it is held together, melting point, conductivity)

Answer 13

has giant lattice structure

held by electrostatic force of attraction

has high melting point

can conduct electricity because the delocaised electrons can move through the structure

Question 14

why does metallic bonding conduct electricity?

Answer 14

Their delocalised electrons carry electrical charge through the metal.
