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.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Is a gold atom or a hydrogen atom larger?
Atomic (covalent) radius of hydrogen is 31 pm. Atomic (covalent) radius of gold is 136 pm.
Is a hydrogen atom bigger smaller or the same size as an oxygen atom?
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
Why are heavy atoms are not appreciably larger than the hydrogen atom?
My theory to why heavy atoms are not appreciably larger than the hydrogen atom is supposedly because that gases can expand and so that hydrogen is a gas, it is larger though if hydrogen were compressed, it should grow appreciably smaller than heavy atoms. Also to make that test fair you would have to make the heavy atom at its gas state so that then you could see the true, fair differ in size between a hydrogen and heavy atom.
Is the mass of a hydrogen atom 16 times greater than an oxygen atom?
No, it is inverse.
Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
Which is larger a hydrogen H atom or a francium Fr atom?
A francium atom (Fr) is larger than a hydrogen atom (H) due to the increase in number of protons and electrons, resulting in larger atomic size. Francium has more electron shells compared to hydrogen, leading to a greater atomic radius.
Why the chlorine does not form hydrogen bond as the nitrogen do in spite the chlorine is more electronegative than nitrogen?
Hydrogen bonding occurs between hydrogen and a highly electronegative atom such as nitrogen, oxygen, or fluorine. Chlorine is less electronegative than these elements, so it is not able to form hydrogen bonds with hydrogen. In hydrogen bonding, the hydrogen atom must be covalently bonded to a highly electronegative atom.
Which is larger a hydrogen atom or francium atom?
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
Can the electron in the ground state of hydrogen absorb a photon of energy 13.6eV and greater than 13.6eV?
yes , the electron in the ground state of the hydrogen atom will absorb a photon of energy 13.6ev but not greater than 13.6 ev . because 13.6 ev is the energy which excites the hydrogen atom
Who has greater kinetic energy a hydrogen atom or a carbon atom moving at the same speed?
The carbon atom would have greater kinetic energy compared to the hydrogen atom because kinetic energy is directly proportional to the mass of the object. Since the carbon atom is heavier than the hydrogen atom, it would possess more kinetic energy when moving at the same speed.
Which is larger a living cell or an atom of hydrogen?
A living cell is much larger than an atom of hydrogen. A living cell can be as much 10,000 times larger in size compared to a single hydrogen atom.
Is the atomic size of magnesium atom greater than that of be?
If by Be you mean beryllium then yes.
Which is larger a hydrogen or francium?
The atomic size of francium is of course greater.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.
