Iodine accepts one electron to achieve noble gas configuration.
Strontium loses two electrons to achieve noble gas configuration.
Nitrogen accepts three electrons to achieve noble gas configuration.
Krypton already has a noble gas configuration.
Nitrogen could achieve a noble gas configuration by gaining three electrons to form a stable octet, similar to the electron configuration of a noble gas such as neon. Alternatively, it could form nitrogen gas molecules (N2) through a triple covalent bond, which also results in a stable configuration with a full outer shell.
if the atom is an element from groups 1, 2, or 13, the atom has to give up electrons to make it have 8. For example, if you have Boron in group 13, it has 3 valence electrons, making it more likely to give up electrons than gain them. If you take 3 electrons from Boron, you get Helium. Helium is the noble-gas for Boron. B(+3) has a noble-gas configuration of He. if the atom is an element from groups 15, 16, or 17, the atom has to gain electrons to make it have 8. For example, if you have Oxygen with 6 valence electrons, it is more likely to gain electrons than lose them. If 2 electrons are added to Oxygen the noble-gas configuration becomes Neon. O(-2) has a noble-gas configuration of Ne. if the atom is an element in group 14, it can either gain or lose electrons. so the noble gas configuration could be the 4 electrons less or 4 electrons more than it. For example, if you add 4 electrons to Carbon you get Neon but if you take away 4 electrons you get Helium.
Krypton could gain a noble gas configuration by either losing 4 electrons to reach the stable configuration of argon or gaining 3 electrons to reach the stable configuration of xenon. This would involve either forming a 4+ cation or gaining a 3- anion.
This is called an "octet" of electrons. It could also be called a "closed shell", since it is characteristic of the outer shell of noble gas atoms.
Atoms are held together by chemical bonds, which are forces of attraction between the positively charged nucleus of one atom and the negatively charged electrons of another atom. The most common types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds. Each type of bond forms as atoms share, donate, or accept electrons to achieve a stable electron configuration.

Alternatively, it could form nitrogen gas molecules (N2) through a triple covalent bond, which also results in a stable configuration with a full outer shell.
The bond that holds atoms together behaves most like a force of attraction between charged particles. This could be ionic bonding, where electrons are transferred between atoms to form oppositely charged ions that are attracted to each other, or covalent bonding, where atoms share electrons to achieve a stable electron configuration.

Who suggested that iodine could be added to salt
Iodine is soluble in carbon tetrachloride.
When two or more atoms combine chemically, they form a molecule. During chemical bonding, atoms share, gain, or lose electrons to achieve a stable configuration, resulting in the formation of chemical compounds.
Atoms can get larger by adding more protons, neutrons, and electrons. However, there is no theoretical limit to how large an atom could be, although the stability of such large atoms would be limited by factors such as nuclear forces and electron configuration.
This is called an "octet" of electrons. It could also be called a "closed shell", since it is characteristic of the outer shell of noble gas atoms.
The oxidation number of lead (Pb) in PbI2 is +2. Iodine (I) typically has an oxidation number of -1 in compounds. Since there are two iodine atoms in PbI2, the total negative charge contributed by iodine is -2. This balances with the +2 charge of lead to make PbI2 neutral.
atoms. diatomic simply means two atoms in one molecule. These could be different things like: Cl2, Br2 and I2.
you could use a magnet to attract the iron if in a mixture stated, and also you could use water to disolve the Iodine and then filter out the iron
