Explanation:
This atom is on the almost extreme right of the 2nd period of the periodic table (except for the stable element on the extreme right). This means it has the highest mass number of the unstable elements of the period. It thus attracts its electron clouds more strongly that the elements to the left of the period . This means it can gain an atom easily ( this is what is called electronegativity – tendency to attract an electron) than is can lose an electron. In addition, it only needs to acquire one electron to achieve a stable electron configuration (8) in its valence shell.
Due to these, it is hard for the atoms to lose an electron which is why it has a high ionization energy- the energy required to lose an electron.

Answer:
I don't know 100% but im pretty sure its electrons, if im wrong im really sorry let me know in the comments ill change it
explanation
the nucleus has more weight but its more compact but the electrons are spread apart circling the nucleus and therefor take up more space

An ideal gas is a theoretical gas composed of many randomly transferring factor particles that aren't difficult to interparticle interactions. the best gasoline idea is beneficial because it obeys the precise gas law, a simplified equation of country, and is amenable to evaluation under statistical mechanics.
An ideal gas is described as one for which both the extent of molecules and forces between the molecules are so small that they have got no effect at the behavior of the gas. The real gas that acts almost like a really perfect gasoline is helium. that is due to the fact helium, in contrast to maximum gases, exists as an unmarried atom, which makes the van der Waals dispersion forces as low as viable
Using the ideal gas equation:-
Given;
P₁ = 1 atm
V₁ = 100 L
n = 3
r = 8.314
T = PV/nR
= 1 × 100 / 3 × 8.314
= 4 K

Answer:
negatively-charged particles.(ELECTRON) B
Explanation:
Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus
The theoretical yield of Carbon dioxide : 0.544 g
<h3>Further explanation</h3>
Given
0.64 g Methane
1.1 g Oxygen gas
Required
The theoretical yield of Carbon dioxide
Solution
Reaction
CH₄ + 2O₂ → CO₂ + 2H₂O.
Find limiting reactant(mol : coefficient)
= mass : MW
= 0.64 : 16
= 0.04
mol : coefficient = 0.04 : 1 = 0.04
= mass : MW
= 1.1 : 32
= 0.034
mol : coefficient = 0.034 : 2 = 0.017
O₂ as a limiting reactant(smaller)
Mol CO₂ based on mol O₂
From equation, mol ratio CO₂ : O₂ = 1 : 2 , so mol CO₂ :
= 1/2 x mol O₂
= 1/2 x 0.034
= 0.017
Mass O₂ :
= 0.017 x 32 g/mol
= 0.544 g
