Which electron on an atom is the most likely one to be removed during a chemical reaction?
The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.
Why formation of uni-negative ion is exothermiic process?
Because when the negative ion is form the atom evolves energy for gaining an other electron.The energy evolves in anionic process so the formation of negative ion is an exothermic process.
What part of the atom do valence electrons occur in?
Valence electrons occur in the outermost energy level, or valence shell, of an atom. These electrons are involved in the formation of chemical bonds and determining the atom's reactivity and chemical properties.
What happens to electrons during ion formation?
During ion formation, electrons are either gained or lost by an atom. When electrons are lost, a positively charged ion forms (cation), and when electrons are gained, a negatively charged ion forms (anion). This process balances the number of protons and electrons in the atom to achieve a stable electron configuration.
The transfer of electrons from one atom to another to achieve a complete outermost energy level is called?
The transfer of electrons from one atom to another to achieve a complete outermost energy level is called ionic bonding. This results in the formation of ions with opposite charges that are attracted to each other to form an ionic compound.
What can be removed from an atom if ionization energy is supplied?
An electron can be removed from an atom if ionization energy is supplied. Ionization energy is the energy required to remove an electron from an atom, resulting in the formation of a positively charged ion.
What is the energy sources for nuclear energy?
energy is released during atom fissure
What is the definition of lonization energy?
Ionization energy is the amount of energy required to remove an electron from a neutral atom, resulting in the formation of a positively charged ion. It is a measure of how tightly an electron is held by an atom. The higher the ionization energy, the more difficult it is to remove an electron from the atom.
Why formation of anion is exothermic?
During the Formation of postitve ion we have to break the force attraction between nuecleus and electron. while doing so energy is absorbed and process become endothermic.
How many electrons of one atom of calcium donate to one atom of oxygen during the formation of the compound CaO?

What do you call the energy involved when an atom loses an electron?
The amount of energy required to remove an electron form an at is the ionization energy.
Which electron on an atom is the most likely one to be removed during a chemical reaction?
The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.
What happens when heat or electrical energy is added to an atom?
When heat is added to an atom, its electrons gain energy and move to higher energy levels, causing the atom to become excited. When electrical energy is added, it can either cause the atom to gain or lose electrons, leading to the formation of ions. Both processes can result in changes to the atom's chemical properties.
Is formation of anions is exothermic process?
The formation of anions is not always an exothermic process. It can be either exothermic or endothermic, depending on the specific elements involved and the overall energy change during the process. It is important to consider the specific reaction and the energy changes associated with it.
In electron transfer involving a metallic atom and nonmetallic atom during ion formation what happens to the atoms?
both atoms gain electrons
How many electrons does one atom of calcium donate to one atom of oxygen during the formation of the compound CaO?
One atom of calcium donates two electrons to one atom of oxygen during the formation of the compound CaO. Calcium loses two electrons to achieve a stable octet configuration, while oxygen gains two electrons to complete its outer shell.
What is the energy in cm-1 of the photon emitted during the transition of an electron in a hydrogen atom from the n3 to n2 energy level?
The energy of the photon emitted during the transition of an electron in a hydrogen atom from the n3 to n2 energy level is approximately 364.5 cm-1.
