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.
The formula for potassium bromide is KBr. It consists of one potassium ion (K+) and one bromide ion (Br-), which combine to form the compound.
The bromide ion has a charge of -1. In the ionic compound potassium bromide (KBr), potassium has a charge of +1 to balance the -1 charge of the bromide ion.
The bromide ion (Br-) has a charge of -1. In the formation of potassium bromide (KBr), the potassium ion (K+) has a charge of +1, and the bromide ion has a charge of -1 to balance the overall charge of the compound.
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.

The charge of a bromide ion in potassium bromide is -1. Bromine typically forms an ion with a -1 charge by gaining one electron to achieve a stable electron configuration.
The bromide ion has a charge of -1. In the ionic compound potassium bromide (KBr), potassium has a charge of +1 to balance the -1 charge of the bromide ion.

The bromide ion (Br-) has a charge of -1. In the formation of potassium bromide (KBr), the potassium ion (K+) has a charge of +1, and the bromide ion has a charge of -1 to balance the overall charge of the compound.
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.
The ionic radius of the bromide ion (Br-) is approximately 196 pm (picometers).
No, potassium bromide does not form a compound by sharing electrons. Potassium bromide is an ionic compound, where the potassium ion donates an electron to the bromide ion, forming an ionic bond.
The potassium ion (K+) is larger than the sodium ion (Na+) because potassium has one more electron in its outer shell compared to sodium. This extra electron creates more electron-electron repulsion, causing the potassium ion to have a larger ionic radius compared to the sodium ion.
Potassium bromide (KBr) is composed of potassium ions (K+) and bromide ions (Br-) in a 1:1 ratio. This means that for every potassium ion, there is one bromide ion in the compound.
The cation in KBr is K+ (potassium ion) and the anion is Br- (bromide ion).
