Answer:
The amount of energy in molecules of matter determines the state of matter.
Explanation:
The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including gas, liquid, or solid-state.
Ans: Elements in the same period have the same number of electron shells.
Answer:
negative, positive, increase
Explanation:
From the given question,
During the formation of bond, between two atoms with difference between their electronegativity-
- The more electronegative atom, will pull the electrons towards itself , and hence acquires a partial negative charge,
And,
- The less electronegative atom, will acquire a partial positive charge.
- The more the difference between the electronegativity of the atoms, the more would be the magnitude of partial charge.
- And, the less would be the difference between the electronegativity of the atoms, the lesser would be the magnitude of partial charge.
Metals are the most abundant
