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.

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.


What weighs more one mole of oxygen or one mole of sodium?

One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.


Is an atom of gold made up of fewer protons than an atom of oxygen?

No, an atom of gold has more protons than an atom of oxygen. Gold has 79 protons, while oxygen has 8 protons.


Why is a oxygen ion larger than oxygen atom?

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.

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.


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

2 times


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.

What is larger then an atom?

pretty much everything is larger than an atom.


Is an electron much larger than an atom?

No, since electrons are part of an atom, they are smaller -- much smaller. In fact, they weigh practically nothing.

One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.


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.
