How many outer shell electrons does iodine have?
The outer most electron shell of iodine atom contains 7 electrons.
How many atoms in a mole of iodine?
Most isotopes of iodine have half lifes ranging typically between a few nanoseconds and a couple of hours. A handful of isotopes can be expected to last for roughly two weeks, and the only stable isotope of iodine is 127I. Assuming then that you mean stable iodine, the relevant numbers are isotope 127 and element number 53 in the periodic table meaning that stable iodine has 127 particles in the core of which 53 are protons. From this we can deduce that one atom of 127I has 127 - 53 = 74 neutrons. I leave it as an exercise to calculate the number of neutrons found in three atoms of iodine.
How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Eight electrons, called an octet, are needed by most atoms in order to be stable.
Where are valence electrons found?
Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.
What is the likely common oxidation number of iodine?
As it forms the I- ion froming an octet its most likely oxidation number is -1
Is iron the most stable atom?
True
Which of these is most likely the correct symbol for an iodine ion?
The symbol for an iodine ion is I- .
Does the presence of an octet makes an atom very likely to react with other elements?
No, quite the opposite. An octet of electrons would make the atom stable, and therefor unlikely to react with most elements.
How many outer shell electrons does iodine have?
The outer most electron shell of iodine atom contains 7 electrons.
Does an atom become most stable when trying to fill its nucleus?
It becomes most stable when its nucleus is filled, not when it is filling it.
What is the most stable state of an atom called?
The ground state.
Is the most atom more or less stable when they have eight valence electrons true or false?
less stable
Is sulfur or nickel in iodine most likely to form a compound?
sulfer
What is the chemical formulas for compounds containing One calcium atom for every two iodine atoms?
The most common compound containing one calcium atom for every two iodine atoms is simply CaI2, or Calcium Iodide.
The isotope most likely to be used to study the thyroid gland is?
Iodine-131
A bromine atom would form its most stable ion by?
gaining 1 electron
Purple colored crystals that are added to water to kill germs?
Most likely crystals of Iodine. Iodine is known for its anti-bacterial properties.
