Final answer:
The third energy level in an atom, as described by quantum mechanics, contains three sublevels: the s, p, and d sublevels.
Explanation:
In the field of chemistry, the term energy level refers to the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. Specifically, when we refer to the third energy level, we're talking about an energy state with the principal quantum number n=3.
For any energy level defined by the principal quantum number n, there are n sublevels. Therefore, in a third energy level (n=3), we have three sublevels. These would be the s, p, and d sublevels.

Answer;
(4) Sodium can combine with chlorine to producea salt.
Explanation;
Sodium is an alkali metal (group 1 ) in the periodic table. It is a soft metal, reactive and with a low melting point. It has an atomic weight of 23 grams.
Sodium is a good conductor of electricity due to the presence of delocalized electrons in its metallic structure. It reacts vigorously with water to produce sodium hydroxide and hydrogen.
-When exposed to air, metallic sodium recently cut looses its silvery appearance and acquires an opaque grey color due to the formation of a sodium oxide coating.

Explanation:
(2) decreased temperature and decreased pressure
(3) increased temperature and increased pressure
(4) increased temperature and decreased pressure
Answers
The changes in temperature and pressure will cause this sample to behave more like an ideal gas by increased temperature and decreased pressure. Hence option 4 is correct.
What is ideal gas?
Ideal gas is defined as a gas that physically behaves in accordance with the ideal, or general, gas law, which is a certain idealized relationship between pressure, volume, and temperature. The ideal gas law can be used to calculate the volume of gases that are produced or used. The ideal-gas equation is frequently used in chemical equations to convert between volumes and molar values.
Ideal gases are those that have little volume and no intermolecular forces. Real gas must have intermolecular attractions and volume in order to exist. At low pressure and high temperature, a genuine gas will act as it should.
Thus, the changes in temperature and pressure will cause this sample to behave more like an ideal gas by increased temperature and decreased pressure. Hence option 4 is correct.

Answer : The correct option is, (4) increased temperature and decreased pressure
Explanation :
The conditions for ideal gas are, it has no intermolecular attractions and have negligible volume.
The ideal gas equation is,
The conditions for real gas are, it has intermolecular attractions and have volume.
The real gas equation is,
A real gas behave ideally at high temperature and low pressure conditions.
From the given options, option (4) increased temperature and decreased pressure is the correct option.
Hence, increased temperature and decreased pressure this sample to behave more like an ideal gas.
