The correct answer is higher melting point, bound by metal metal bonds.
While alkali metals only have one valence electron, alkaline earth metals have two. Metal to metal connections hold the metals together. Alkaline earth metals have a stronger metallic connection and a higher melting point because they have two valence electrons.
the characteristics that Group 2 metals excel in over Group 1 metals.
- Initial Ionization Potential
- Group 2 items are more difficult than group 1 elements.
- Strong propensity to produce bivalent compounds
As a result, group 2 metals have stronger metallic bonding, which leads to increased cohesive energy and compact atom packing. This explains why group 2 metals are harder and have higher melting and boiling temperatures than group 1 metals.

I think its the sea cucumber and sea urchin
but it could be the star too
in this case yes, ecigs are way healthier than cigs even if cigarette fans want to say otherwise, the thousands upon thousands of foreign and dangerous chemicals in cigarettes is terrifying to any health nut, there is 2 different types of petroleum in the filter along with thousands of fiberglass shards that are embedded into every layer of that filter is scary alone.
