Answer: The ionization energies of anions of group 17 elements will be higher than for neutral atoms of the same group.

Explanation:

The ionization energy is the energy required to remove an electron from the valence shell of an isolated gaseous atom of an element.

Ionization energy depends on:

a) Electronic configuration of an element: If on losing or gaining of an electron an element attains noble gas configuration or half filled stability then it will be difficult to remove the electron from stable configuration.

b) size of an element :larger the size more lesser the effective nuclear charge on electron thus lower the ionization energy.

Group 17 elements have 7 valence electrons and thus on gaining one electron , they attain stable noble gas configuration and thus the ionization energy will become higher.

Isotope atoms mean, atoms with the same number of protons but different number of neutrons in their nuclei . The given oxygen atoms are isotopes meaning they have different number of neutrons in their nuclei . Oxygen 16 have 8 protons and 8 neutrons in its nucleus but Oxygen has 8 protons and 10 neutrons. That's what make them different.

What are 5 things in our house that uses electrical energy and how
seropon [69]

Answer:

Heating.

Cooling.

Water Heater.

Washer and Dryer.

Lights.

Refrigerator.

Electric Oven.

Dishwasher.

Charging devices

Explanation:

People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.

How it works is a current of electricity is a steady flow of electrons. When electrons move from one place to another, round a circuit, they carry electrical energy from place to place like marching ants carrying leaves. Instead of carrying leaves, electrons carry a tiny amount of electric charge

Hope this helped some!

Your answer is, all of the above.

<u>Chemical Change </u>

A chemical change occurs on the molecular level and produces a new substance. However, a physical change rearranges molecules and does not produce a new substance.

                    <u>10 examples of chemical changes</u>

  • Burning of paper and log of wood
  • Digestion of food
  • Boiling an egg
  • Chemical battery usage
  • Electroplating a metal
  • Baking a cake
  • Milk going sour
  • Various metabolic reactions that take place in the cells
  • Rotting of fruits
  • Decomposition of waste

                      <u> Impacts of Chemical changes</u>

Anytime a new substance is made, a chemical change takes place. Usually two or more materials are combined and a new substance is formed. A chemical change can produce amazing explosions, like fireworks.

Thus, <u>all of the above</u> is the correct answer. Learn more about "Chemical Changes" here
