They are easily lost because they are the furthest away from the nucleus, making them the easiest to remove. To visualize that, imagine you have paperclips around a magnet. The furthest one will be the easiest to take off, and it will become harder to take them away as they get closer to the magnet.

What is an atom called that has lost valence electrons?
An atom that has lost valence electrons is called a cation. This causes the atom to have a positive charge due to having more protons than electrons.
Does the electron determine the reactivity of an atom?
The number of electrons an atom has in its outer shell, and how easily those electrons can be gained or lost, determines an atom's reactivity. Electrons play a crucial role in forming chemical bonds, and the availability of electrons in the outer shell influences how likely an atom is to react with other atoms.
Do an atom's valence electron have high or low energy?
Valence electrons generally have higher energy compared to core electrons because they are located in the outermost shell of an atom and are involved in chemical bonding. Their higher energy allows them to be more easily lost or shared during chemical reactions. This makes them crucial for determining an atom's reactivity and the types of bonds it can form.
Number of electrons lost or gained by an atom in a chemical reaction is its?
The number of electrons lost or gained by an atom in a chemical reaction is its oxidation number. This represents the charge an atom would have if the bonding electrons were completely transferred. It helps to understand how atoms combine and react with each other.
Where in an atom does the transfer of electrons occur?
The transfer of electrons in an atom primarily occurs in the outermost shell, known as the valence shell. This region contains the valence electrons, which are involved in chemical bonding and interactions with other atoms. During chemical reactions, these valence electrons can be gained, lost, or shared between atoms, facilitating the formation of ions and molecules.
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
What is an atom called that has lost valence electrons?
An atom that has lost valence electrons is called a cation. This causes the atom to have a positive charge due to having more protons than electrons.

If valence electrons are gained or lost the atom becomes a charged particle called a?
an ion.
What is an atom that has lost or gained one or more valence electrons called?
covalent bonds
What is the relationship of valence electron and oxidation number?
The valence electrons of an atom determine its ability to form bonds and participate in chemical reactions. The oxidation number of an atom indicates the number of electrons it has gained, lost, or shared in a chemical compound. The valence electrons of an atom can help determine its oxidation number by considering how many electrons the atom needs to reach a stable configuration.
Is the reactivity of a metal depend on how easily it loses its valence electrons?
Yes, the reactivity of a metal does depend on how easily it loses its valence electrons. Metals that lose electrons easily are more reactive because they can form positive ions more readily. This is why alkali metals, which have only one valence electron, are highly reactive.
Do an atom's valence electron have high or low energy?

Their higher energy allows them to be more easily lost or shared during chemical reactions. This makes them crucial for determining an atom's reactivity and the types of bonds it can form.

How many valence electrons are shared gained or lost by each atom of glucose?
In glucose (C₆H₁₂O₆), each carbon atom shares four valence electrons, each hydrogen atom shares one valence electron, and each oxygen atom shares two valence electrons. Specifically, carbon forms four covalent bonds with neighboring atoms, hydrogen forms one bond, and oxygen typically forms two bonds. Overall, glucose involves the sharing of a total of 24 valence electrons in its molecular structure. There are no electrons gained or lost in the process; it primarily involves sharing through covalent bonding.
EXPLAIN why it is not possible to determine the type of atom by knowing the charge of the atom?
Knowing the charge of an atom only provides information on the number of electrons it has gained or lost. Different types of atoms can have the same charge if they have gained or lost electrons in the same proportion. Therefore, the charge alone is not sufficient to determine the type of atom.
What is happening to valence electrons in a purely ionic bond?
In the atom which will form the positive ion, the valence electrons is/are being given up and lost to the reaction medium (environment). In the atom which will form the negative ion, the valence electrons lingering in the reaction medium will be attracted to the proton of the negative ion and is taken in by the negative ion.
