Explanation:
Answer: true
Explanation:
In chemical reactions, an energy barrier exists between reactants and products. The magnitude of this energy barrier determines the rate of reaction. A lesser energy barrier implies that reactants are converted to products faster since the energy required is not too much. On the other hand, a large energy difference between reactants and products will lead to a slow reaction with very poor yield of products if any.
Answer:
alkali metal
Explanation:
The alkali metals in period 4 will have the lowest ionization energy of the elements in the period.
Across a period ionization energy increases progressively from left to right due to decreasing atomic radii caused by the increasing nuclear charge which is not compensated for by successive electronic shells.
- Ionization energy is the energy needed to remove the most loosely bound electrons of an atom in the gas phase in the ground state.
- The measure of the readiness of an atom to lose an electron is the ionization energy.
Down a group, it decreases.
