∙ 11y agoA cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.

A) It is Large (Correct)B) It is smaller
C) It is the same size

Wiki User
∙ 13y agoBecause electrons are so very tiny, it will minutely change the size, if the atom did not lose or gain an energy level. If it did, there would be a change, but still not that much.

∙ 10y agoThe size of a negative ion is larger than atom. This makes more negative than positive, allowing the negative electrons to go farther from the nucleus.

How does the size change when an atom forms a cation and when an atom forms an anion?
A metal atom is smaller than the cation formed from it, because the electron(s) lost from a metal atom to form its cations are from the outermost electron shell or energy level of the atom. These electrons increase the size of the atom compared with the cation.
When an atom gains one or more electron to form a negative ion what happened to its size?
overall, the electrons have a larger charge than an uncharged ion, so the overall force between the positive nucleus and the electrons is higher (opposite forces attract) the electrons move slightly closer to the nucleus, therefore slightly reducing the atom's diameter.
Why Na positive ion is smaller than a Na atom in size?
Na (Atomic number: 11; Electronic configuration: 1s2, 2s2, 2p6, 3s1). Na has 11 electrons distributed in electron shells. This negative charge provided by electrons is countered by 11 protons present in nucleus of Na. The electron in 3s1 is losely held by the positively charged nucleus. When Na loses its outermost electron (3s1), there is an imbalance in the total number of positive charge (provided by protons) and negative charge (provided by electrons). With an increase in positive charge in the ion, the electron charge around the nucleus is drawn closer to it. As a result of this the atomic radius of the Na ion decreases and hence its radius is smaller than that of Na atom.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
If the nucleus of an atom were the size of a marble then the atom itself would be the size of?
The atom itself would be the size of an NFL stadium.
How does the size ofa negative ion compare to the size of the atom that formed it?
It is larger, because it has gained electrons.
How does the size if a negative ion compare to the size of the atom that formed it?
It will be have gained one electron. So, it will weigh 1/1875 unit more than the entire whole atom .
How does the size of a negative ion compare to the size of the atom that form?
The size of a negative ion is larger than atom. This makes more negative than positive, allowing the negative electrons to go farther from the nucleus.
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.
How does the size of each compare with the size of the neutral atom form which it is formed?
A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.
How does the size of the nucleus of an atom compare to the size of the electron cloud?

How does the size change when an atom forms a cation and when an atom forms an anion?
A metal atom is smaller than the cation formed from it, because the electron(s) lost from a metal atom to form its cations are from the outermost electron shell or energy level of the atom. These electrons increase the size of the atom compared with the cation.
How does the size of a cation compare with the size of the neutral atom from which it is formed?
An ion is an atom that carries a charge because it has more or less electrons than its neutral form. An electron weighs less than 0.06% of a proton and doesn't take up any real space, therefore an ion is not different in size than its neutral atom.
Compare a very large and a small atom in the large atom the outermost electron is farther away from the nucleus?
yes, if by larger you mean size/volume.
How does the size of an atomic nucleus compare with the size of the whole atom?
Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
What is an atom called when it no longer has a neutral charge?
An atom with no electric charge will be called a neutral atom. In a neutral atom, there is a balance of charges, and the number of protons will be equal to the number of electrons. It's really that simple. Compare this to atoms that have an imbalance of charges. These atoms are called ions.
How does the size of a beryllium atom compare with the size of an oxygen atom?
Oxygen is fairly smaller than Beryllium. The two have the same amount of orbital shells, but Oxygen has more protons, which pulls its electrons closer together, thus decreasing the overall size!
