what does the atomic number tell you?

Answer 4

• what no. the element is on the periodic table

• the number of electrons surrounding the nucleus

Question 5

what does the mass number tell you?

Answer 5

the mass number tells us the number of protons and neutrons found in the nucleus

Question 6

what are isotopes?

Answer 6

atoms that belong to the same element however have a different number of neutrons in the nucleus meaning it has a different mass number .

Question 7

list all the particles in an atom from lightest to heaviest?

Answer 7

1. electron
2. proton
3. neutron
4. atom

Question 8

describe the meaning of when electrons are in their ground state?

Answer 8

when electrons are in their ground state they are in located in the shells closest to the nucleus

Question 9

describe the meaning of excited electrons?

Answer 9

• valence electrons can be excited when heat energy is applied to the atom allowing the valence electrons to promote to a higher level (an outer shell further away from the nucleus), when the electron returns to its ground state it emits energy in the form of light

transition groups

Question 27

when does metallic bonding occur?

Answer 27

occurs between metal atoms

Question 28

when does ionic bonding occur?

Answer 28

occurs between non-metal and metal atoms

Question 29

what are ions?

Answer 29

are atoms that have gained or lost an electron giving them a positive or negative charge

Question 30

what happens to the name of a negative ion in ionic compounds?

Answer 30

the negative ions name changes to 'ide'

Question 31

characteristics in ionic bonding? | 4

Answer 31

- metal + non-metal elements - non-metallic atoms have a strong hold on their valence electrons - non-metallic atoms gain electrons from metal atoms - electrostatic forces pull the P & N ions together each ion is surround by ions of the opposite charge which creates a 3D structure called a lattice

Question 32

what is the name for a POS ion?

Answer 32

- cation

Question 33

what is the name for a NEG ion?

Answer 33

- anion

Question 34

characteristics in metallic bonding?

Answer 34

- metal atoms have a weak hold on their valence electrons - metal atoms become positive ions - positive ion makes it an opposite charge with the electrons - this makes the electrons attract creating electrostatic force, which provides multidirectional bonding between POS ions and delocalised electrons

Question 35

what does ductile mean?

Answer 35

when metal elements can be drawn out into a thin wire

Question 36

in every group all the elements have the same number of electrons in the ......

Answer 36

outer shell

Question 37

periods are the....

Answer 37

horizontal columns

Question 38

groups are the....

Answer 38

vertical columns

Question 39

what makes an ion a good electrical conductor?

Answer 39

when the charges are able to freely move it makes it a good electrical conductor eg. metallic bonding with the delocalised electrons

Question 40

which group forms ions that have a charge of -2?

Answer 40

group 16

Question 41

which group forms ions that have a charge of +3?

Answer 41

group 13

Question 42
