Question

What does a strong positive and strong negative field around a cation or anion mean?
Why small cations have strong field and large cation have weak field ?

Answer 1

1. what does a strong positive and strong negative field around a cation or anion mean?

• Caution are positively charged and anions carry a negative charge

Answer 2

Explanation:

an atom, or atoms, has a balanced number of electrons (negative charge) and protons (positive charge) they are neutral overall. However, if they are not balanced, they will be charged. These charged species are called ions.

What is an anion?

An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them. The number of electrons gained, and so the charge of the ion, is indicated after the chemical symbol, e.g. chlorine (Cl) gains one electron to become Cl-, whilst oxygen (O) gains two electrons to become O2-.
