What else can I help you with?
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
Which orbital is filled when bromine gains an electron to become a negative ion?
The extra electron added to bromine when it becomes a negative ion will fill the 4p orbital. Bromine typically has the electron configuration [Ar] 3d10 4s2 4p5, so gaining an electron will complete the 4p subshell, resulting in a stable Br- ion.
What is bigger a chlorine atom or a chlorine ion?
A chloride ion is slightly larger than a chlorine atom, because in an ion there is one more electron than proton, allowing the electron shells to expand slightly. In a chlorine atom, the number of electrons and protons is the same.
How does hydrogen ion change into a hydrogen atom?
A hydrogen ion (H+) gains an electron to become a hydrogen atom (H). This process is known as reduction, where the electron is added to neutralize the positive charge of the hydrogen ion, resulting in the formation of a stable hydrogen atom.
Why electron affinity of dinegative ion is endothermic?
When an electron is added to a dinegative ion, it is already in a very stabilized state due to the presence of two extra electrons. Adding another electron would result in electron-electron repulsions and destabilize the system, requiring energy input. This leads to an endothermic process for adding an electron to a dinegative ion.
What is the third ionization energy for fluorine?
Second ionization energy of fluorine is the amount of energy needed to remove an electron from a unipositive fluorine atom (F+)to form F2+,in all the gaseous state
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
What is needed to form a negative ion?
An electron is added in an atom to form a negative ion or anion. Because electron carry negative charge.
How many electrons are in the uni-positive ion of sodium?
There are less electrons than protons in a positive ion. More information is needed to determine the exact number. Here is an example: How many electrons are in a carbon ion with a positive charge of positive 2e? There are 6 protons in carbon (since it is element number 6). Since it has a charge of +2, there will be 2 less electrons than protons, so the number of electrons would be 4.
What is the formula for iodide ion?
I-1 It is Iodine with an electron added to complete the outer shell.
Electron arrangement that gives an atom stability?
An anion is an ion that has a negative charge. It is formed when valence electrons are added to the outer energy level. It is giving the ion a stable electron configuration.
Which orbital is filled when bromine gains an electron to become a negative ion?
The extra electron added to bromine when it becomes a negative ion will fill the 4p orbital. Bromine typically has the electron configuration [Ar] 3d10 4s2 4p5, so gaining an electron will complete the 4p subshell, resulting in a stable Br- ion.
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.
What is bigger a chlorine atom or a chlorine ion?
A chloride ion is slightly larger than a chlorine atom, because in an ion there is one more electron than proton, allowing the electron shells to expand slightly. In a chlorine atom, the number of electrons and protons is the same.

A hydrogen ion (H+) gains an electron to become a hydrogen atom (H). This process is known as reduction, where the electron is added to neutralize the positive charge of the hydrogen ion, resulting in the formation of a stable hydrogen atom.
What happens to bromine when bromine atom gains an electron and forms the bromide ion Br -?
When a bromine atom gains an electron to form the bromide ion (Br-), it becomes negatively charged. The added electron gives the ion a full outer shell of electrons, making it stable. The bromide ion will be attracted to positively charged ions or molecules.
Why electron affinity of dinegative ion is endothermic?
When an electron is added to a dinegative ion, it is already in a very stabilized state due to the presence of two extra electrons. Adding another electron would result in electron-electron repulsions and destabilize the system, requiring energy input. This leads to an endothermic process for adding an electron to a dinegative ion.
