State and explain the general trend of atomic radius in Group 2? |
Atomic radius increases down the group. More electron shells -> greater shielding so bigger atomic radius |
|
|
State and explain the general trend in 1st ionisation energy in Group 2. |
1st IE decreases down the group. Atomic size increases -> greater shielding so weaker attraction between the nucleus and the outer electrons. Less energy required to remove the 1st electron. |
|
|
State and explain the general trend in melting point of Group 2 metals. |
Melting point decreases down the group. Weaker metallic bonding as metal ions are bigger so weaker attraction between the delocalised electrons and the nucleus, so lower melting points. |
