That depends: is it a positive ion (Br+) or a negative ion (Br-)? An ion with a charge of +1 has one less electron than the element would have normally. An ion with a charge of -1 has one more electron than normal. It seems kind of strange that -1 means one more, and +1 means one less, but that's because an electron has a charge of -1, so if there is one less electron than is needed to keep the atomic charge balanced, the charge will be positive by 1. Cations (pronounced cat-ions, not cashons), ions with a positive charge and therefore fewer electrons than the neutral atom, have a smaller atomic radius than the neutral atom. Anions, ions with a negative charge and therefore more electrons than usual, have a larger atomic radius than the neutral atom. So a bromine cation would have a smaller radius, and a bromine anion would have a larger atomic radius.
NOTE: when referring to a neutral atom, the atom is of THE SAME ELEMENT as the ion. Otherwise, the comparison is not necessarily true.
What else can I help you with?
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.
Why is a bromide ion larger than a bromine atom?
Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.
What is larger radius a sodium ion or chloride ion?
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.
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.
Does a sulfide ion have a bigger radius than a sulfur atom?
The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom. This extra repulsion in the sulfide ion increases the average distance between the valence electrons, so the electron cloud around the sulfide ion has the greater radius.
Which one has the larger radius potassium ion or bromide ion?
The bromide ion has a larger radius than the potassium ion. This is because bromine has more electron shells than potassium, resulting in a larger atomic radius and thus a larger ionic radius for bromide compared to potassium.
Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.
What one is larger a chlorine atom or a chloride ion?
A chloride ion is larger than a chlorine atom because it has gained an electron, leading to increased electron-electron repulsion and a larger ionic radius compared to the atomic radius of a chlorine atom.
Why is a bromide ion larger than a bromine atom?
Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.
What is going to happen to the size of a positive ion as compared to the original atom?
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
What is the radius of a potassium atom is larger than a radius of potassium ion in the ground state?
This occurs because a potassium atom has one more electron than a potassium ion in the ground state; the extra electron increases the size of the atom due to increased electron-electron repulsion, leading to a larger atomic radius than the potassium ion.
Who has the largest radius calcium atom or calcium ion?
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
What is larger radius a sodium ion or chloride ion?
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.
Is bromine a atom or ion?
"Bromine" is the name of an atom or an element. The corresponding ion is named "bromide".
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.
Compare the size of the radius of a negative ion to its neutral atom?
The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same
