Answer:

Same number of electrons in their outer shell.

Explanation:

Whe working out their electronic configuration ( by looking at the atomic number) , one will find out that the number of electrons in their outer shell is also the same so the elements have to lose or gain the same amount of electrons to become stable.

Glowing light patterns called auroras form in the _____.
amid [387]

Answer: The correct answer is option (D)

Explanation:

These aurora are also known as polar lights or northern lights( north poles) or southern lights(south pole) . This is caused by the interaction between the charged particles from the sun with particles present in the upper atmosphere of the earth's atmosphere. The layer in which these interaction takes place is Thermosphere (with high temperature).

Hence, the correct answer is option (D).

We have a sample of water vapor which cools from 150 °C to 125 °C. What happens to the motion of the molecules during this time
pentagon [3]

The motion of the molecules decreases.

<u>Explanation</u>:

  • Gases are formed when the energy in a system overcomes the attractive forces between the molecules. The gases expand to fill the space they occupy. In this way, the gas molecules interact little. In the gaseous state, the molecules move very quickly. As the temperature decreases, the amount of movement of the individual molecules also decreases.
  • The fast-moving particle slows down. When a particle speeds up, it has more kinetic energy. When a particle slows down, it has less kinetic energy. The particles in solid form are commonly connected through electrostatic powers. They don't get enough space to move around, therefore, their speed diminishes, they can't keep their standard speed like in the vaporous or fluid state.
