What is the second quantum number of a 2s^2 electron in phosphorus,

Chemistry

My name is Ann [436]2 years ago
8 0

Answer:

l = 0

Explanation:

Second quantum number, also known as angular momentum quantum number (l), represents the shape of an orbital. Several quantum numbers and their corresponding orbital shapes are worth remembering:

  • l = 0, this is an s-shaped orbital;
  • l = 1, this is a p-shaped orbital;
  • l = 2, this is a d-shaped orbital;
  • l = 3, this is a f-shaped orbital

Notice that the angular momentum quantum number might be identified solely from the letter. Since we're considering a 2s orbital, this means we're dealing with an s orbital. As defined above, s-shaped orbital would have an l value of l = 0.

Which of the following will stay constant, no matter if the substance is in the solid, liquid, or gas state? volume shape temper
Harman [31]

Answer : The correct option is, Mass

Explanation :

As we know that there are 3 states of matter :

Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state have a definite shape and volume.

Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state have a definite volume but does not have a fixed shape.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. This state have indefinite volume as well as shape.

If we are taking 100 grams of ice then after melting its mass remains same but its shape, volume and temperature will be changed and after evaporation its mass remains same but its shape, volume and temperature will be changed.

Hence, the mass will stay constant, no matter if the substance is in the solid, liquid, or gas state.

An ion with 11 protons 12 neutrons and a charge of + 1 has an atomic number of
posledela

Answer:

11 electrons total and 23amu

Explanation:

This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu.
