An electron has several shells with electron. When these shells are completely filled, the most outer shell doesnt relatively feel much attraction of the electrons towards the nucleus. Therefore it is possible that one electron gets out of the shells.
If this is done, the atom has too little amount of electrons, it needs one more. The attraction force is then increased, which means it takes a lot of more energy to remove the second electron, let alone the third
Usually only one electron is removed from an atom in chemical reactions because the removal of electrons occurs one at a time and involves specific energy requirements. Removing additional electrons would require significantly more energy and is less favorable due to the increased repulsion between the remaining electrons.

What will happen if all the electrons of an atom are removed?
If all the electrons of an atom are removed, the atom will become positively charged because it would then consist only of protons in its nucleus. This would result in an ion with a charge equal to the number of protons in the nucleus.
What is the only part of the atom that can be rubbed or pulled off?
The only part of an atom that can be removed or added is an electron. Electrons are negatively charged particles that can be gained or lost during chemical reactions.
What is energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
How many atoms are in an atom of beryllium?
Only two electron shells.
What is the only part of an atom that can be removed or added?
The valence electrons.
What is the valance electron of lithium atom that is easily remove to form a lithium with a charge of 1?
The valence electron of a lithium atom is in the 2s orbital. It is easily removed to form a lithium ion with a charge of +1 because lithium only has one valence electron, making it relatively easy to lose.

The only part of an atom that can be removed or added is an electron. Electrons are negatively charged particles that can be gained or lost during chemical reactions.
How many bonds do hydrogen usually form?
Hydrogen typically forms one bond with another atom, as it only has one electron to share with another atom to achieve a stable electron configuration.
When a potassium atom reacts with a bromine atom the potassium atom will?
lose only one electron
What is the only subatomic particle that can jump from atom to atom?
An electron can jump from atom to atom.
True or false a atom is ionized if one of its electrons jumps to a higher energy level in the atom?
True. Ionization occurs when an electron is either removed from or added to an atom, resulting in the atom becoming positively or negatively charged, respectively. An electron jumping to a higher energy level within the atom does not result in ionization.
What is energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
How many electrons that a hydrogen atom shares?
Hydrogen atoms have one valence electron which is also the only electron they have.
Because a hydrogen atom does not contain a neutron hydrogen ions can be thought of as what?
a Proton. A hydrogen-1 atom (the most abundant isotope of hydrogen) has no neutrons and only 1 proton. So the atom is 1 proton and 1 electron. So the ion, when the electron is removed, the entire ion is just 1 single proton.
If a sodium atom loses its only valence electron to another atom what does it become?
If a sodium atom loses its only valence electron, it becomes a sodium cation (Na+). This is because it has lost a negative electron, leaving behind a positively charged ion.
How many valence electrons does an atom of potassium have?
