How does the size vary with the number of electron added in the formation of anion?
As electrons are added to form anions, the increased negative charge leads to greater electron-electron repulsions, causing the electron cloud to expand. This expansion results in an increase in the size of the anion compared to its neutral atom counterpart.
What happens when an electron is added to an atom it will acquire?
when an electron is added to an atom, the atom will acquire a negative charge.
What causes an atom to have a negative charge?
An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.
Definition of electron affinity?
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
What is the energy needed to remove an electron from a negative ion to form a neutral atom or molecule?
The energy needed to remove an electron from a negative ion to form a neutral atom or molecule is called the electron affinity. It represents the energy change when an electron is added to a neutral atom or molecule to form a negative ion. The higher the electron affinity, the greater the energy needed to remove an electron.
If an electron is added to a neutral atom the atom becomes what?
it will become a negative ion due to the negative charge of electron
When electron is added to unipositive ion we get?
When an electron is added to a unipositive ion, the resulting atom gains a negative charge and becomes a neutral atom. The electron neutralizes the positive charge of the ion, balancing the overall charge of the atom.
What is the charge of an element if it loses an electron?
It depends on the charge on the atom at the start before it gains an electron. The electron has a charge of -1, and will make an atom more negative or less positive (both of which are the same thing). Let's look at the possibilities. If an atom is neutral (zero net charge) and gains an electron, it has a net charge of -1. If an atom is at +1 and gains an electron, it has a net charge of zero. If an atom has any positive charge, p, above +1, it has a net charge of p - 1. (A +5 would become a +4, and a +3 would become a +2.) If an atom has any negative charge, n, then its net charge becomes n - 1. (A -4 would become a -5, and a -2 would become a -3.)

How is the electron configuration for both a cation and a anion differ from its neutral atom?
Let us assume that we have Sodium (Na), it has the ground state electron configuration of: [Ne]3S1. The ANION is negative, and thereby has more electrons, the Na anion(Na.) would have the following electron configuration: [Ne]3S2. The CATION(which is a positive ion) of Na(Na+) would have [Ne] as it electron configuration(as it loses an electron and becomes "equal" to Neon)
When an electron atom is added to a neutral atom energy is?
It becomes an anion.
What is the electron configuration for 02-?
The electrons configuration for O2- is [He]2s22p6.
What happens when a neutron is added to a neutral atom?
well, since a neutron = 0 charge placed into a neutral which is has no charge, it stays the same.
Is ionization energy required to add an electron to a netural atom?
Ionization energy is an expression linked to extraction of an electron.
What happens to the size of nonmetals as they become ions?
Nonmetals tend to gain electrons to become negatively charged ions, increasing in size due to the addition of the electron(s). This is because the added electron(s) repel the existing electrons, causing the electron cloud to expand and the ion to be larger than the neutral atom.
What causes an atom to have a negative charge?
An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.
