The atom which it would be most difficult to remove an electron from is: an atom of a noble gas.
An atom refers to a smallest, indivisible unit that comprises the matter that forms all chemical elements.
Basically, the three (3) distinct particles that makes up an atom include;
Electrons are the subatomic particles of a chemical element that are negatively charged with a magnitude of -1.
Noble gases can be defined as a group of chemical elements with eight (8) valenceelectrons, which simply means they are found in group eight (8) of the periodic table and have a full octet.
Some examples of noble gases are:
The octet rule states that atoms of chemical elements lose, gain or share electrons, in order to have eight (8) electrons in their valence shell.
Based on the octet rule, it would be most difficult to remove an electron from the atom of a noble gas because of its high ionization energy and a completely filled valence (outermost) shell.
In conclusion, the full octet possessed by noble gases make them unlikely to combine with other chemical elements.

Answer:
The number of atom is 3.67*10^24 atoms
Explanation:
Molar mass of methane CH4 is 16.0g/mol
Using this to divide the mass
24.4g/16.0 = 1.525mol
1 mol CH4 contains 1 mol of Carbon C and 4 mol of hydrogen H, so 1.525mol contains 4(1.525)=6.1 molH
Using avogadro number : (6.1mol)(6.02*10^23)
= 3.67*10^24 atoms
There are 3.66 × 10^24 hydrogen atoms in 24.4 g of methane (CH4). This is calculated by first finding the number of moles of CH4 and then using Avogadro's number to determine the total number of molecules, which is finally multiplied by 4 (the number of hydrogen atoms per CH4 molecule).
The question asks how many atoms of hydrogen are in 24.4 g of methane (CH4). Methane has a molecular formula of CH4, indicating that each molecule contains 4 hydrogen atoms. The molar mass of methane is 16.04 g/mol (12.01 g for carbon + 4 × 1.008 g for hydrogen).
First, calculate the number of moles of methane:
24.4 g CH4 × (1 mol CH4 / 16.04 g CH4) = 1.52 mol CH4
Then, multiply by Avogadro's number to find the total number of methane molecules:
1.52 mol CH4 × (6.022 × 1023 molecules/mol) = 9.15 × 1023 molecules of CH4
Since each molecule of methane has 4 hydrogen atoms, we get:
9.15 × 1023 molecules CH4 × (4 H atoms/molecule) = 3.66 × 1024 hydrogen atoms.
Explanation:
Plasma is a state of matter which is a hot ionized gas and it contains molecules with positive ions and negative electrons.
Since there is high kinetic energy of molecules so, there is swirling gas of positive ions and negative electrons. As a result, there will be release of electrons.
For example, lightening is an example of partially ionized plasma.
When molecules gain significant kinetic energy, their collisions may cause ionization, releasing electrons and forming a plasma, the fourth state of matter. Similar processes can be observed in devices like a Van de Graaff generator or in nature, such as in the sun.
When the kinetic energy of molecules increases significantly, it can cause a phenomenon known as ionization. Energy fueling these molecules increases their pace, effectively leading to collisions among themselves and increasing their speed even more. As these collisions grow in strength, they can cause electrons to be released or ejected, thereby transforming neutral atoms into ions.
Visualize this using the concept of a Van de Graaff generator, which uses a source of positive charge and a moving belt to create a spray of positive charge that achieves high velocities. In conditions of intense kinetic energy, such as those induced by high temperature or light intensity, similar processes occur at the atomic level: atoms, ions, and molecules move and collide, breaking old bonds, forming new ones, and sometimes releasing electrons in the process.
The existence of a gas containing both positively charged ions and negatively charged electrons in this state is often referred to as a plasma. Plasmas are common in extremely hot environments and are considered the fourth state of matter alongside solid, liquid, and gas. Examples of plasmas include the sun and the colorful lights you see in neon signs.
