The size of an atom can be greater than that of its parent atom due to the addition of electron shells or energy levels. When an atom gains electrons, particularly in the case of anions, the increased electron-electron repulsion can lead to a larger atomic radius. Additionally, if the atom undergoes ionization and gains protons, the increased positive charge can pull electrons closer, but if more electron shells are added, the overall size still increases. Therefore, the addition of electrons and the resulting changes in electron distribution can affect atomic size.
What else can I help you with?
Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
Why size of hydrogen ion is greater than its atom?
It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.
A negative ion is than its parent atom?
A negative ion has gained one or more electrons to become negatively charged, while its parent atom is neutral with an equal number of protons and electrons. This means the negative ion has more electrons than its parent atom.
Why is the radius of an atom of iodine greater than the radius of bromine atom?
An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
Why size of hydrogen ion is greater than its atom?
It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.
Is the atomic size of magnesium atom greater than that of be?
If by Be you mean beryllium then yes.
When an atom gains one or more electron to form a negative ion what happened to its size?
When an atom gains one or more electrons to form a negative ion, its size generally increases. This is because the additional electrons cause greater repulsion between the electrons, resulting in an increase in the overall size of the atom.
Is a positive ion smaller or larger than its parent atom?
A positive ion is smaller than its parent atom because it has less electrons than its parent atom. The reduced number of electrons are then pulled more tightly to the positive nucleus because the number of protons remains the same, and these now exceed the electrons in number.
Which atom is the smallest in size?
The atom that is smallest in size is the hydrogen atom.
What makes an iron atom have a greater mass than an aliminium atom?
The amount of protons in the nucleus of an iron atom is greater than in that of an aluminum atom.
What is a parent atom?
A parent atom is a term used to describe the original state of an atom or element before it undergoes a chemical change. For instance, it may be used when discussing radioactive decay. The original element would be the parent atom, and the element that results from the radioactive decay would be the daughter atom. It may also be used when discussing ions. The parent atom would be the element before it undergoes ionization, and the daughter atom would be the resulting cation or anion.
Is a negative ion larger or smaller than its parent atom?
A negative ion is typically larger than its parent atom. When an atom gains an electron to become a negative ion, the added electron increases the electron-electron repulsions, causing the electron cloud to expand. This expansion results in a larger ionic radius compared to the neutral atom.
The volume of an atom is determined by the size of?
By the size of the atom and its mass
A negative ion is than its parent atom?
A negative ion has gained one or more electrons to become negatively charged, while its parent atom is neutral with an equal number of protons and electrons. This means the negative ion has more electrons than its parent atom.
Which has a greater atomic radius at atom of fluorine or an atom of beryllium?
An atom of fluorine
