What charge is F after it gets an electron from Li?
The negative charge increases by 1. So it is -1
What happens to ionic radius if you add an electron?
Adding an electron to an atom increases its negative charge, leading to an increase in electron-electron repulsions. This results in the outer electron shell expanding, causing the ionic radius to increase.
What is The ratio of the specific charge of an electron to that of a positron is?
The ratio of the specific charge of an electron to that of a positron is 1:1. Both the electron and positron have the same magnitude of charge but opposite in sign, with the electron being negative and the positron being positive.
How do you work out specific charge?
To work out the specific charge of a given element, you will take the positive electron charge and multiply it by the negative electron charge. This can be calculated by the formula q=ne
What is mean by specific charge of an electron?
The specific charge of an electron is its charge-to-mass ratio. It quantifies how the charge of an electron compares to its mass and is approximately -1.76 x 10^11 coulombs per kilogram. This property plays a crucial role in understanding the behavior of electrons in electromagnetic fields.

Why does the first ionization energy increase as you go across a period?
Because as the nuclear charge increases, the attraction between the nucleus and the electrons increases and it requires more energy to remove the outermost electron and that means there is a higher ionization energy. As you go across the periodic table, nuclear charge is the most important consideration. So, going across the periodic table, there should be an increase in ionization energy because of the increasing nuclear charge.
What is ratio of specific charge of an electrorn to that of proton?
The specific charge of an electron is 1.759 x 10^11 C/kg, while the specific charge of a proton is 9.58 x 10^7 C/kg. Therefore, the ratio of specific charge of an electron to that of a proton is approximately 1.8 x 10^3.
In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding increases down a group in the periodic table, as more electron shells are added. This reduces the effective nuclear charge experienced by the outermost electron, making it easier for that electron to be removed or participate in chemical reactions.
What emits electrons in specific charge of electron experiment?

If an electron is gained the atom has a charge.?
If an atom gains an electron, it becomes negatively charged and is referred to as an anion. This occurs because the addition of an electron increases the number of negatively charged particles in the atom, resulting in an imbalance between the positive charge of the protons and the negative charge of the electrons. Consequently, the overall charge of the atom shifts from neutral to negative.
What does atomic size depend on?
Atomic size depends primarily on the number of electron shells and the effective nuclear charge experienced by the outermost electrons. As you move down a group in the periodic table, atomic size increases due to the addition of electron shells, which outweighs the increase in nuclear charge. Conversely, across a period, atomic size generally decreases as the effective nuclear charge increases, pulling the electrons closer to the nucleus. Additionally, electron-electron repulsion in multi-electron atoms can also influence atomic size.
