What can be a personal question about atoms
Damm [24]

Heres a list of questions

1. Define atom.

Atom is the smallest particle of a substance.

2. What are the subatomic particles found in an atom?

The subatomic particles found in an atom are electrons, protons, and neutrons.

3. Define charged particle.

Charged particle is a particle that has an electric charge.

4. Define electric charge.

Electric charge is the physical property of particles such as electrons and protons. Electric charge causes other particles to experience a force.

5. What are the charged particles found in an atom?

Electrons and protons are the charged particles found in an atom.

6. What are the different types of charged particles?

Charged particles are of two types: positive charges and negative charges.

7. What are the negatively charged particles in an atom?

Electrons are the negatively charged particles in an atom.

8. What are the positively charged particles in an atom?

Protons are the positively charged particles in an atom.

9. What is the mass of an electron?

The mass of an electron is 9.107 × 10-31 kilograms.

10. What is the mass of a proton?

The mass of a proton is 1.672 × 10-27kilograms.

11. Define atomic number.

The total number of protons in the nucleus of an atom is called atomic number.

12. Define neutron number.

The total number of neutrons in the nucleus of an atom is called neutron number.

13. Define mass number.

Mass number is the total number of protons and neutrons in the nucleus of an atom.

What is the density (g/mL) of an object that has a mass of 0.03 kg and occupies a volume of 25 mL?
tatyana61 [14]
First convert the kg to g ----- 0.03kg = 30g
Then divide the mass by the volume ----- 30g ÷ 25mL = 1.2
The density is 1.2g/mL<span />

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>----------------------------------------------------------------------</h2><h2>ELECTROPLATING </h2>

Electroplating the plating one metal on to the another metal, It is mostly used for preventing corrosion by using copper or chromium or decorate the object by using gold or silver plating.

__________________________________________________________

<h3>Principle:</h3>

When electricity is passed the thin layer of metal is deposited on another metal and water molecule given out as a By-Product, Thus this process works on the principle of Hydrolysis.

<h2>_____________________________________</h2><h2>QUESTION:</h2>

A) Electrolysis

B) Chromium prevents corrosion and gives the fine shining touch to the objects.

C) The metal which is deposited to the object i.e. spoon will be connected to the positive electrode of a battery, Thus it is anode. The spoon at which electroplating is need to be done is connected to the negative electrode, thus the Spoon is cathode.

What is the oxidation state of each element in the species Mn(ClO4)3?
gayaneshka [121]
The oxidation state of the compound Mn (ClO4)3 is to be determined in this problem. For oxygen, the charge is 2-, the total considering its number of atoms is -24. Mn has a charge of +3. TO compute for Mn, we must achieve zero charge overall hence 3+3x-24=0 where x is the Cl charge. Cl charge, x is +7.
