Step by step explain
A. CI, Br
Explanation:
Different kinds of atoms bind their valence electrons with various amounts of energy. In order to remove the valence electrons, enough energy must be available.
The amount of energy required for the removal of an electron is the ionization energy or ionization potential.
The ionization energy depends on:
- Nuclear charge
- Atomic radius
- Sublevel accomodating the electron to be removed.
- Special stability of half or fully filled sublevels.
Across a period, the ionization energy increases.
Down a group ionization energy decreases due to increasing atomic radii.
Cl and Br are in the same periodic group. Cl is element number 2 and Br is element 3 in the group of the halogens.
Therefore, Cl will have a higher ionization energy compared to Br.

Answer:
Because of the less reactivity of copper.
Explanation:
As well as being resistant to the elements and thereby less likely to be affected by rainfall, hail, and mildew than other types of roofing, copper is also one of the most fireproof materials available. Copper is also highly resistant to thermal changes and thereby doesn't deteriorate quickly.
Magnesium would also corrode PDQ. Magnesium sheeting would also pose an unacceptably high fire hazard.
Answer:
he can bang metal pipes but i would rather say that he has to yell for help
Explanation:
why because the basement is very loud and echo so when is parents hear him they can run to basement and get him out
hope this helped
Sugar. It is solid and its atoms have less kinetic energy to overcome the bonding force. So, the bonding force is stronger than water, which is liquid and has more kinetic energy to overcome the bonding force of atoms. So, water has less strong force of attraction. Hence, sugar has stronger forces of attraction.
