Which of the following particles has almost no mass? proton neutron electron

Answers

Answer: Electron has almost no mass.

Explanation:

Mass is defined as the actual matter that is contained in a substance. At an atomic level, it is expressed in atomic mass units.

The given options are the 3 subatomic particles.

Mass of the given subatomic particles are:

Proton = 1.007276u

Neutron = 1.008664u

Electron = 0.0005485u

Mass of neutron is slightly more than the mass of proton.

From the above information, it is visible that electron has a negligible mass.

Hence, the correct answer is electron.

Answer:

Electron has almost no mass.

Explanation:

3 x 1023 molecules of element Z have a mass of 38 g. What is the mass of 1 mole?

Answers

38 g / (3 x 10^23 molecules) * 6,02x10^23 molecules/mol = 76,25 g/mol.

Answer:

76.3 g of 1 mole of element Z

Explanation:

According to Avogadro’s number the number of particles in 1 mole of a substance is 6.023 x 10²³.

The mass of 3 x 10²³ particles is 38g

Therefore, the mass of 6.023 x 10²³ is $( 38 g x 6.023 x 10^2^3)/(3 x 10^2^3)$ = 76.3 g

Sulfur has 3 energy levels.

Answer:

Explanation:

Metallic bonding is possible because the electrons

Answers

It is possible because the electrons in the energy level furthest from the nucleus delocalise, this leaves behind positively charged metal ions which are attracted to the negatively charged electrons that now move around the lattice freely

If element x has 55 protons how many electrons does it have

Answers

Answer: 55

Explanation: A atom consists of a nucleus and electrons.Nucleus contain neutrons with no charge and protons with positive charge. The electrons bearing negative charge revolve around the nucleus.

An electrically neutral atom contains equal number of protons and electrons. Thus if a neutral element X contains 55 protons, it also contains 55 electrons.

If the element has 55 protons it is celcium and it also has 55 electrons. It has an atomic mass of 133 (132.9) so to get the number of neutrons you subtract the atomic mass and the number of protons.

How many phosphorus atoms are there in 1.75 mol of calcium phosphate,
Ca3(PO4)2

Answers

There will be two atoms of phosphorus in the 1.75 mol of calcium phosphate.

What are atoms?

Atoms are the smallest unit of matter. In a chemical reaction, the number of atoms shows the quantity of an element in the compound or reaction. Phosphorus is a chemical element that is preset in the periodic table.

In calcium phosphate, Ca3(PO4)2, the number of atoms can be calculated by counting the number of moles that is given in the equation.

The number of atoms of calcium is 3, and the number of phosphorus atoms is 2.

Now given the 1.75 mol of calcium phosphate, so the number of atoms of phosphorus will be the same in any number of moles of calcium phosphate. So there will be 2 atoms of phosphorus in the given equation.

Thus, the number of atoms is two.
