Answer:- .
Explanation:- Atomic number for fluorine(F) is 9 and it's electron configuration is .
is formed when F loses one electron from it's valence shell.
Second shell is the valence shell for fluorine and so it loses one electron from 2p to form and the electron configuration of the ion becomes
.
Final answer:
The ground state electron configuration of F+ is 1s²2s²2p⁴, which is derived from the neutral Fluorine's configuration 1s²2s²2p⁵ by removing one electron from the outermost 2p orbital.
Explanation:
The question asked for the full ground state electron configuration of F+. The neutral Fluorine atom (F) has 9 electrons. Its electron configuration is: 1s²2s²2p⁵. When Fluorine loses one electron it becomes a positively charged ion (F+), so its electron configuration will be: 1s²2s²2p⁴. This is because the electron is removed from the outermost shell, specifically the 2p orbital. This ground-state electron configuration refers to the most stable arrangement of electrons around the nucleus.

Chemical formula for nitrogen gas is N₂.
To find the number of molecules in the given sample, we have to convert the mass of the sample to moles by using the molecular mass of elemental nitrogen (N₂).
Now, we have to use Avogadro's number (6.022x10^23) that indicates the number of molecules in one mole of substance:
It means that there are 2.79x10^24 molecules of elemental nitrogen.
To find the number of atoms we just have to multiply the number of molecules by 2, which is the number of atoms of nitrogen per molecule of elemental nitrogen:
There are 5.59x10^24 atoms of nitrogen in the sample.

Answer:
every atom has no overall charge. because they contain equal numbers of positive protons and negative electrons. they cancel each other out making them a neutral atom.

Answer:
Ions of opposite charge strongly attract each other; those of like charges repel. As a result ions in an ionic compound are arranged in a particular manner.

One mole of carbon would contain 6.02 x 1023 carbon atoms, but one mole of chlorine would contain 6.02 x 1023 diatomic chlorine molecules.
For ionic compounds, the representative particle is the formula unit of the compound (eg. NaCl).
One mole of water (H2O) contains 6.02 x 1023 atoms.
Avogadro's number is the number of discrete, representative units found in one mole of a substance.
Answers
Answer:
Option C
Explanation:
Avogadro number represent discrete unit of a substance which can be atom, molecule, ion etc.
In one mole of H2O there will be 6.02 x 1023 molecules and not atoms.
Molecule of H2O is the discrete unit of water mole and not atom.
Hence, option C is correct choice of answer

The rule used for the determination of the protons, electrons, and neutrons has been the equal number of protons and electrons, while the number of the neutrons has been the difference in the atomic mass and the protons.
The atom has been the smallest particle that has comprised of electrons, protons, and neutrons as the subatomic particle. The neutrons and protons in the atoms have consisted within the nucleus. The electrons in the atom are revolving around the nucleus.
The atoms have been consisted of an equal number of protons and electrons, while the number of neutrons has been the difference in the atomic mass and the protons.
The ions have been formed with the loss or gain of the electrons by the atom in the terms of valence electrons to complete its octet.

Explanation:
This question appears incomplete, however
The number of protons of an element/atom (atomic number) can be determined by checking for the position of the element on the periodic table. This is because elements are arranged according to there atomic number on the periodic table.
The number of electrons of any element (of a neutral atom) is equal to the number of protons of the same element.
The number of neutrons of an element/atom is determined by subtracting the atomic number of the element from it's mass number. Hence, mass number is the addition of the atomic number and the number of neutrons.
Ions are charged particles that have the same number of protons and neutrons as there parent atoms. Hence, they have different number of electrons when compared to there specific parent/neutral atom.
A negatively charged atom has more electrons than it's original atom. For example, fluoride ion (F⁻) has 10 electrons while fluorine atom has 9 electrons (meaning fluoride ion has one more electron than it's parent fluorine). The increase is dependent on the number "attached" to the charge. A positively charged atom has less electrons than it's original atom. For example, calcium ion (Ca²⁺) has 18 electrons while calcium atom has 20 electrons (meaning the calcium ion has 2 electrons less than it's parent calcium atom). As said earlier, the decrease here is also dependent on the number "attached" to the charge.
