Answer:
Explanation:
Hello, there are two properties of alkaline metals that make them have that behavior:
1. They have large electrode potential which allows them to displace the hydrogen in the water.
2. They released energy when the hydrogen is displaced is big enough to make it ignite.
Now, the reaction is more violent when increasing the period of the alkaline metal because the higher the period (atomic radius as well) the higher the electrode potential which increases the released energy.
Best regards.

Answer:
The correct answer is:Oxygen is more electronegative than carbon. See the explanation below, please
Explanation:
The electronegativities of oxygen and carbon are: 3, 44 and 2, 55 respectively. The electronegativity is defined as the capacity that a given atom has for the attraction of electrons, by forming a chemical bond. Polarity is related to electronegativity. The greater the difference in electronegativities between two atoms, the polarity of the bond they form will be greater.
