Answer:

By conducting thermal energy from inside the house and release it outside the house.

Explanation:

The aluminum is a good conductor of thermal energy, so the coils made by this metal helps the heat change between the inside and the outside of the house. Because the inside has a higher temperature, the heat flows from inside to the outside, and then the house keeps cool.

X, Y & Z represents 2, 12 & 17 relatively a. Write the electronic configuration of x, y, and z b. Place the elements in

olasank [31]

The electronic configuration of x, y, and z.

$x=1s^2$

$Y= 1s^22s^22p^63s^2$

$Z= 1s^22s^22p^63s^23p^5$

<h3>What is an electronic configuration?</h3>

Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.

$x=1s^2$

$Y= 1s^22s^22p^63s^2$

$Z= 1s^22s^22p^63s^23p^5$

x= Period 1 and group18

Y=Element is in period 3 and Group 2

Z=Element is in period 3 and group 17.

X, Y & Z represents Helium, magnesium, and chlorine.
