Answer is: d. a lower melting point and boiling point.
Alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.
Bond between these elements is metallic bond.
Both the melting and boiling points decrease down the group 1, because the decrease in the strength of each metallic bond.
From top to bottom, atomic radius increase and the distance between the nucleus and delocalized electrons increases, so metallic bond is weaker (attractions fall).
Metallic bond is formed between electrons and positively charged metal ions.
Explanation:
The answer is mentioned above.

Combustion of fossil fuels
Explanation:
The most likely source of the carbon dioxide shown in the graph is the combustion of fossil fuels for both industrial and domestic use.
- Fossil fuels are hydrocarbon units.
- They burn in the presence of oxygen gas to from carbon dioxide and water.
- The level of carbon dioxide has been increasing dramatically with increase in industrialization.
- The fuels are used and needed for the workings of machinery.
- Domestically they are used in heating homes and powering automobiles.
- These processes produce carbon dioxide as a waste product.
