Answers

Answer:

The answer would be C) a liquid.

Explanation:

If you were to pour a glass of water into a rectangular container, the water would fill up the container and be in the same shape as the container. That is becuase water flows and it doesn't harden up or take its own shape until it's frozen. The molecules are not tightly secure to each other so they are able to move freely.

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option A.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Atoms can make many different molecules, just like letters can make many different words.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

Therefore, the correct option is option A that is Atoms can make many different molecules, just like letters can make many different words.

How many moles would there be in 500,000,000,000 atoms of silver? Show your calculation
and answer in unit

Answers

Answer: 3.01 * 10^35

Explanation:

500,000,000,000 * 6.02 * 10^23

There are 3 [tex]\rm \times\;10^3^5[/tex] moles of silver present in the 500,000,000,000 atoms of silver.

According to the concept of molar mass:

1 atom = [tex]\rm 6.023\;\times\;10^2^3[/tex] moles

500,000,000,000 atoms of silver can be written as:

5 [tex]\rm \times\;10^1^1[/tex] atoms of silver.

1 atom = [tex]\rm 6.023\;\times\;10^2^3[/tex] moles

5 [tex]\rm \times\;10^1^1[/tex] atoms = 5 [tex]\rm \times\;10^1^1[/tex] [tex]\times[/tex] [tex]\rm 6.023\;\times\;10^2^3[/tex] moles

5 [tex]\rm \times\;10^1^1[/tex] atoms = 30.115 [tex]\rm \times\;10^3^4[/tex] moles

= 3 [tex]\rm \times\;10^3^5[/tex] moles.

The moles of silver are present in the 500,000,000,000 atoms of silver are 3 [tex]\rm \times\;10^3^5[/tex] moles.

why gold is called inert metal​

Answers

Gold has a heavy enough nucleus that its electrons must travel at speeds nearing the speed of light to prevent them from falling into the nucleus. This relativistic effect applies to those orbitals that have appreciable density at the nucleus, such as s and p orbitals. These relativistic electrons gain mass and as a consequence, their orbits contract. As these s and (to some degree) p orbits are contracted, the other electrons in d and f orbitals are better screened from the nucleus and their orbitals actually expand.

Since the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can't be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.

Hope it helps

Gold is relatively inert metal because, the one valence electron in 6s orbital  is not available for bonding since it is more attracted by nucleus. The 4f and 5d orbitals are completely filled and does not involve in bonding.

What is inertness ?

Some elements tends to be unreactive compared to the other by their extra stability factors. This unreactness is called inertness. The 18th group elements are all inert since they are highly stable due to completely filled electronic configuration.

Gold is 79th element in periodic table. It is a transition metal located in d-block. The electronic configuration of gold is [Xe] 4f¹⁴ 5d¹⁰ 6s¹. There is only valence electron which is in the 6s orbital.

The 4s orbital experience more nuclear pull which leads to the unavailability of the valence electron. The 4f and 5d orbitals are completely filled and does not involve in chemical bonding. That's why gold is called inert metal.
