At what temperature does iron turn into a gas? What does this tell you about the attraction between iron’s particles?

Answer: In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. The oxygen and nitrogen molecules in air at normal room temperature are moving rapidly at between 300 to 400 metres per second. Unlike collisions between macroscopic objects, collisions between particles are perfectly elastic with no loss of kinetic energy.

Explanation: This is very different to most other collisions where some kinetic energy is transformed into other forms such as heat and sound. It is the perfectly elastic nature of the collisions that enables the gas particles to continue rebounding after each collision with no loss of speed. Particles are still subject to gravity and hit the bottom of a container with greater force than the top, and giving gases weight. Hope this helps with your problem! Byeeee :DDD

Answer: Option (c) is the correct answer.

Explanation:

Atomic number of sodium is 11 and its electronic configuration is $1s^{2}2s^{2}2p^{6}3s^{1}$ . When sodium loses one electron then it will attain +1 charge and its electronic configuration will be as follows.

$Na^{+}$ : $1s^{2}2s^{2}2p^{6}$

Atomic number of fluorine is 9 and its electronic configuration is $1s^{2}2s^{2}2p^{5}$ . When fluorine gains an electron then it acquires -1 charge and its electronic configuration is as follows.

$F^{-}$ : $1s^{2}2s^{2}2p^{6}$

Atomic number of aluminium is 13 and its electronic configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{1}$ . When aluminium loses its valence electrons then it acquires +3 charge and its electronic configuration is as follows.

$Al^{3+}$ : $1s^{2}2s^{2}2p^{6}$

Thus, we can conclude that the listing for aluminum is correct.

What does it mean for a element of a group to have a order?

lisabon 2012 [21]

In group theory, a branch of mathematics, the term order is used in two unrelated senses:

The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that am = e (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.The ordering relation of a partially or totally ordered group.

This article is about the first sense of order.

The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
