How does the ionic radius of a typical anion compare with radius for corresponding neutral atom?
The ionic radius of a typical anion is larger than the radius of the corresponding neutral atom. This is because when an atom gains an electron to become an anion, the extra electron increases the electron-electron repulsion, causing the electron cloud to expand, resulting in a larger ionic radius.
When an atom becomes a cation what happens to it's radius?
When an atom becomes a cation, it loses one or more electrons, causing the outermost electron shell to contract. This contraction of the electron cloud results in a decrease in the atomic radius of the cation compared to the neutral atom.
What happens with the electrons when an atom froms a cation and an anion?
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
How does a atom become an cation or an anion?
an atom becomes a cation when the atom loses electrons during a reaction, and it becomes an anion when the atom gains electrons in a reaction it accepts an additional electron.
How is the size of an anion different from the size of the atom from which it was formed?
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
Why do the properties of an anion differ from those of its parent atom?
The anion has a negative electrical charge and is more chemically reactive than the atom.
If an atom has four valence electrons is it an anion?
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
What is the atom with the most electrons than protons is called?
If you mean an atom with more electrons than protons it is called an ion. More specifically an anion (negatively charged)
What is the relationship between atomic radius and the corresponding model radius?
Atomic radius refers to the size of an atom, while model radius is the size of the atom as represented in a molecular or atomic model. In most models, the model radius is larger than the atomic radius in order to make the structure more visible and distinguishable. The relationship between the two is that the model radius is typically proportional to the atomic radius but scaled up for clarity.
When an atom has more electrons that protons it is?
An anion is an ion with more electrons than protons.
What a negative charged atom?
A negatively charged atom is called an anion, which is an atom that has more electrons than protons.
When an atom has more electrons than protons it is?
An atom with more protons than electrons is a cation.
