How many protons, neutrons and electrons are there in a neutral Cesium atom?

55 protons, 78 neutrons, 55 electrons

69 protons, 100 neutrons, 69 electrons

37 protons, 37 neutrons, 45 electrons

43 protons, 65 neutrons, 43 electrons

Answers

Answer 1

Answer:

55 protons, 78 neutrons, 55 electrons

Explanation:

In a neutral Cesium atom we have 55 protons, 78 neutrons and 55 electrons. This can be found on the periodic table of elements.

Protons are the positively charged particles within an atom

Neutrons do not carry any charges.

Electrons are the negatively charged particles.

The amount of these subatomic particles can be obtained from the periodic table of element.

For a neutral atom, the number of protons and electrons are the same.

Since the atomic number is 55, it is also the number of protons in the atom.

Calculate the Molar Mass in g/mol of Ammonium Sulfate, (NH4)2(SO4)

Answers

Answer:

132g/mol

Explanation:

The problem here is to find the molar mass of the compound in g/mol

To solve this problem, we simply sum the atomic masses of the atoms in the compound:

   (NH₄)₂ SO₄:

  Atomic mass of N  = 14g

   Atomic mass of H  = 1g

  Atomic mass of S  = 32g

  Atomic mass of O = 16g

So;

   Molar mass = 2[(14 + 4(1))] + 32 + 4(16)  = 132g/mol

How many electrons does one neutrally charged atom of argon have?
A 18
O B.22
C. 40
D. 58

Answers

Answer:

A. 18

Explanation:

A neutral charged atom is an atom with 0 charge.

Anyway, first look at the periodic table and find Argon.

After you find Argon, look at its Atomic number.

Its Atomic number is 18.

And a neutral atom of Argon has 0 charge.

So we need 18 electrons for Argon to cancel out and become neutral.

Basic math:

18 +( -18) = 0

Therefore, the correct answer is A. 18

Hope it helped!

One neutrally charged atom of argon (Ar) has 18 electrons. (Option B)

What is argon?

Argon is an element with atomic number 18, which means it has 18 protons in its nucleus.

In a neutral atom, the number of electrons is equal to the number of protons. Therefore, a neutrally charged atom of argon will also have 18 electrons orbiting around the nucleus.

The number of electrons in an atom is determined by its atomic number and is essential for the atom's chemical properties and interactions.

Argon is commonly used as an inert gas in various applications, including welding, lighting, and as a protective gas in the manufacturing of electronics.

The compound MnO2 could either have a +4 or a +2 oxidation state on the manganese (Mn) atom. Explain how either scenario could occur.

Answers

Answer:

See explanation

Explanation:

Manganese is a transition element. All transition elements have incompletely filled d orbitals which ultimately makes them to exhibit a variable oxidation state.

Manganese has electronic configuration of [Ar]4s23d5. This means that two electrons could be lost from the s orbital to yield Mn^2+. Also, two electrons could be lost from both s and d orbitals to yield Mn^4+

Answers

Answer:

Explanation:

The reaction expression is given as:

           ⁴⁰₁₈ Ar   →   X  +  ⁰₁B  

To solve this problem, we must bear in mind that both mass number and atomic number must be conserved.

 So;

For the mass number:

               40  = A + 0

                 A  = 40

For atomic number:

                 18  = Z + 1

                  Z = 18 - 1  = 17

An atom is identifiable by the atomic number. Since the atomic number of X is 17 then it is Cl, chlorine

How does the number of tin atoms in the sample compare to the number of aluminum atoms in a 20 gram sample of each (Sn:Al)

Answers

The number of Al atoms is greater than the number of Sn atoms

Further explanation

Given

20 gram sample of Tin and Aluminum

Required

Number of atoms

Solution

1 mol = 6.02 x 10²³ particles (atoms, molecules, ions)

So the number of atoms of each element is determined by the number of moles. The greater the number of moles the greater the number of atoms

moles Sn-Tin(Ar = 118,71 u)

mol = mass : Ar

mol = 20 : 118,71 u

mol = 0.168

moles of Al-Aluminum(Ar=26.9815 u)

mol = 20 : 26.9815 u

mol = 0.741

So the number of Al atoms > number of Sn atoms

3 reasons why aluminium is used in making of cooking vessels

Answers

Answer is : It is a good thermal and electrical conductor. -The main point to be noted is that aluminium is a highly reactive element and still it is used for making cooking utensils. The reason is that aluminium has a very high affinity for oxygen. So, it reacts with oxygen and forms a layer of aluminium oxide on its surface.

Answer:

This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide . This oxide layer is very stable and prevents further reaction of aluminium with oxygen . Also , it is light in weight and a good conductor of heat Hence , it is used to make cooking utensils .

The compound F2O has two lone pairs on the central oxygen atom. What's the structure of an F2O molecule? Is this compound polar or non-polar? Question 1 options: A) Bent or angular, polar B) Trigonal planar, polar C) Bent or angular, non-polar D) Trigonal planar, non-polar

Answers

Answer:  A) Bent or angular, polar

Explanation:

The central atom oxygen has two lone pairs and two bond pairs in [tex]OF_2[/tex]. The number of electron pairs are 4,  that means the hybridization will be [tex]sp^3[/tex] and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.

The compound [tex]OF_2[/tex] is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.
