Cl -
This means that Chlorine has an extra electron, so it's negative.
Chlorine already has 7 electrons and in order to be stable, it only needs one more electron.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
A. 35Cl1 is the symbol that represents a chlorine ion that has gained an extra electron to achieve a stable electron configuration.
When Chlorine is in its ionized state, it gains one electron to become a chloride ion (Cl-). Therefore, in its ionized state, Chlorine has 18 electrons in total.
The sodium atom, Na, is ionized, giving it's electron to the chlorine, Cl. Therefore, one electron is transferred from the sodium to the chlorine, forming Na+ and Cl- ions and an ionic bond.
Iodine is a halogen (group 7 of the periodic table), and halogens are supposed to have seven valenced electrons to match the amount of protons in their nucleus. However, in order to form a full octet of valence electrons, iodine atoms are willing to accept one more electron. This electron brings iodine's charge down to -1. And unlike other halogens that are smaller than iodine (fluorine, chlorine, and bromine), iodine is large enough so that its negative charge can be distributed more evenly. This makes iodine stable with a negative charge, and a good leaving group in chemical reactions (something you will probably learn later on in organic chemistry).
Cl-1.

A. 35Cl1 is the symbol that represents a chlorine ion that has gained an extra electron to achieve a stable electron configuration.
Chlorine becomes an anion when it is ionized, as it gains one electron to achieve a more stable electron configuration.
When Chlorine is in its ionized state, it gains one electron to become a chloride ion (Cl-). Therefore, in its ionized state, Chlorine has 18 electrons in total.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
The most common number is one, chlorine achieves the octet, as in the HCl molecule. However there are chlorine oxides and chlorine fluoride compounds where more than one covalent bond id formed. One example is chlorine trioxide with 6, another is chorine pentafluoride with 5.
Chloride is the ionized form of chlorine.
Ionizing is when you rip an electron away. so by taking an electron away, the atom is ionized
The Noble Gases (Group VIIIA or Group 8A) do not exchange electrons or become ionized into ions since they already have a full electron configuration.
The sodium atom, Na, is ionized, giving it's electron to the chlorine, Cl. Therefore, one electron is transferred from the sodium to the chlorine, forming Na+ and Cl- ions and an ionic bond.
Calcium loses 2 valence electron to become ionized.
