Answer:
E)Li
Explanation:
Electronegativity is the tendency of an atom to attract a pair of bonding electrons. In the periodic table, electronegativity increases across the period and decrease down the group.
This means the element at the top of the group would have the highest electronegativity.
The correct option is;
E)Li
Each column is called a group<span>. The elements in each </span>group have<span> the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.</span>
Answer:
Combustion
Explanation:
The reaction type is a combustion reaction;
Ethanol + oxygen gas → carbon dioxide + water
Now;
Ethanol is the fuel and oxygen gas rapidly combines with it to form carbon dioxide and water.
- This process releases heat energy from chemical bonds.
- Most hydrocarbons burn in excess air or oxygen to give carbon dioxide and water.
