In an oxide ion, electrons get added. This means, lesser nuclear charge. This is due to screening effect. The inner electrons shield the outer electron from the nuclear charge which is why the outer electrons get relatively lesser nuclear charge. So, more electrons means lesser nuclear charge.

Consider a person standing in front of you. You get blocked from the view in front of you. Suppose two more people stand in front of you. Now, it is more difficult for you to catch a glimpse of the front view than it was before.

This is exactly what happens in the oxide ion.

Lesser nuclear charge means the electrons do not get pulled towards the nucleus as they were before, i.e., in the oxide ion, the electrons do not get pulled towards the nucleus as they were in the neutral oxygen atom.So, the electrons will be farther than they originally were.Thus, an oxide ion is larger than an oxygen atom.

Why oxygen size is bigger then zn size in Zinc oxide structure?

The larger size of oxygen compared to zinc in zinc oxide is due to the atomic radius difference between the two elements. Oxygen has a larger atomic radius than zinc, resulting in larger O atoms in the zinc oxide structure. Additionally, the bonding arrangement in the crystal structure of zinc oxide may also contribute to the perception of oxygen atoms appearing larger.


Is lead oxide a metal?

Lead oxide is not a metal. Why?Lead is metal by itself, lead oxide is metal oxide, meaning it is a chemical compound that contains at least one atom of oxygen (thus oxide) and one other element (being a metal oxide, that one other element has to be metal, in this case lead).


Why in a water molecule is the oxygen atom bigger then the nitrogen atom?

First of all, there is no nitrogen in a water molecule. A water molecule consists of one oxygen atom combined with two hydrogen atoms. Also known as H2O. However, it is also true that an oxygen atom is slightly bigger than a nitrogen atom. Oxygen has one more proton, and one more electron than nitrogen does. Neutron quantities vary, since there is more than one isotope of both oxygen and nitrogen.


Is a sodium atom is larger than a silicon atom?

No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.


Ion of oxygen?

An ion of oxygen with a positive charge is called a "positively charged oxygen ion" or "oxygen cation." This type of ion is less common than the negatively charged oxygen ion (oxygen anion). It forms when an oxygen atom loses one or more electrons.

Is a molecule of oxygen larger than a molecule of hydrogen?

Yes, a molecule of oxygen (O2) is larger than a molecule of hydrogen (H2) because an oxygen atom has a larger atomic radius and can form stronger bonds with other atoms, resulting in a larger molecule size.


An oxygen ion is larger than the oxygen atom since?

an oxygen ion has gained electrons, increasing the electron-electron repulsion and making the electron cloud expand. This causes the ion to be larger than the neutral atom.


How many times larger is the hydrogen atom than the oxygen atom in a polysaccharides?

2 times


Is double oxide a atom or molecule?

If you mean O2, then it is a molecule, though it would be more appropriate to call it "double oxygen" than "double oxide." Though it is usually just called oxygen. If you main O22-, then it is an ion, not a molecule or atom. It is called the peroxide ion.


Is an oxygen atom bigger than a hydrogen atom?

An oxygen atom has 8 of each neutrons, electrons, and protons. While a carbon atom has only 6 of each. I had the same problem! So i hope this helped :)


Is smaller than the atomic radius of oxygen?

Yes, the atomic radius of oxygen is larger than the size of an atom. The atomic radius represents the distance from the nucleus to the outermost electron shell of an atom.


Which noble gas has an electron structure like the ions in magnesium oxide?

Neon: In forming magnesium oxide from the elements, two electrons leave each magnesium atom and transfer to an oxygen atom. Therefore, both the magnesium cation and the oxygen anion have the electron configuration of neon, which has an atomic number 2 greater than oxygen and 2 less than magnesium.


What The more positive atom in a molecule of dihydrogen oxide?

In a molecule of dihydrogen oxide (H2O), the oxygen atom is more positive than the hydrogen atoms due to its higher electronegativity. Oxygen attracts the shared electrons more strongly, resulting in a partial negative charge on oxygen and partial positive charges on the hydrogen atoms.

What is the equation for the combustion of oxide?

The general equation for the combustion of an oxide is: Oxide + Oxygen → Oxide + Energy. This represents the reaction where the oxide reacts with oxygen, typically producing heat or light energy. The specific chemical equation would depend on the specific oxide being combusted.
