An anion IS an ion.
Yes, an anion is an ion with more electrons than protons giving it a negative charge.
When an ion has more electrons than protons in it, the whole ion (charged particle) is negatively charged. The number of negative charges (electrons) exceeds the number of positive charges (protons).
Yes, an anion is an ion that has more electrons than protons, which gives it a negative charge.
If you mean an atom with more electrons than protons it is called an ion. More specifically an anion (negatively charged)
IT is a negatively charged ion consisting of more than one atom
An atom with more protons than electrons is a cation.
An anion is an ion with more electrons than protons.
An atom with extra (a higher number than that of its protons) electrons is an anion. An atom with a lower count than its protons is a cation. They are often reffered to as positive (cation) or negative (anion) Ions. An Ion is defined as a charged particle.
No. The Se ion will be larger than the Br ion. The more negative the anion's charge, the larger the radius (more electrons = stronger repulsion between the electrons; so, more distance between them). Se would become "Se2-" as an anion, and Br would become "Br1-". Because Se's "2-" anion charge is more negative than Br's "1-" anion charge, and because Se would have more relative electrons to protons than Br, there is more repulsion between electrons, and distance, within the Se ion. So, the Se ion has a larger radius. Hope it helps.
an anion is simply an atom of an element which has 1 or more excess electrons in addition to its own electrons.this is the reason an anion has negative charge equals to the number of excess electrons it has.
An ion. If there are less electrons than protons, the atom gains a positive charge and is called a cation. If there are more electrons than protons, the atom gains a negative charge and is called an anion.
This ion is an anion.
