How can a substance gain energy and still be frozen
emmasim [6.3K]
When a substance is under less pressure, or is under higher heat, it is gaining energy still. The particles vibrate faster, and get slightly more spaced out. If you take a metal ball and ring that fits perfectly around the ball, then heat the ball up with a flame, you will notice that the ball doesn't fit through the ring. The ball is still solid, but because it had more heat, it had more energy.

Misha Larkins [42]
Simple,

take a look at your periodic table, if you have it labeled look at the Halogen

Now, a period on the periodic table is read from left to right, and goes

down the rows of the periodic table.

Go to Period 5, go all the way to the Halogens, what is there?

Which of the following halogens is darkest in colour?
Naddik [55]

I₂ is the halogens which is darkest in colour than other.

<h3>What is halogen? </h3>

Halogens are the elements which belongs to group 17. Group 17 elements are known as halogens. They are highly electronegative in nature.

The last electronic configuration is ns2 np5. Since, one electron is less to get stable electronic configuration. Therefore, they accept one electron and get stable electronic configuration.

<h3>Why halogens are dark in colour? </h3>

As we move down the group, the darkness of colour increases. This is due to ionization energy which decreases as we move down the group. This is due to increase in the atomic size and decrease in nuclear form which further make high energy level to absorb lesser light and reflects deepen colour on moving down the group. Due to which they appears dark. Therefore, option A is the correct option.

Thus, we can concluded that I₂ is the halogens which is darkest in colour than other.
