What would be the atomic mass of an atom with 6 protons 6 electrons and 8 neutrons?
Carbon-12: with 6 protons and 6 neutrons and an atomic mass of 12. Carbon-14: with 6 protons and 8 neutrons, and an atomic mass of 14.
What is the atomic mass of an atom with 6 protons 6 neutrons and 6 electrons?
Carbon-12 is of particular importance in its use as the standard from which atomic masses of all nuclides are measured, thus, its atomic mass is exactly 12 daltons by definition. Carbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons.
What is the mass of an atom with 5 protons 6 neutrons and 6 electrons?
The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons). In this case the mass number would be 11.

How does iodine exist in nature?
Occurrence and distribution. Iodine is never found in nature uncombined, and it is not concentrated sufficiently to form independent minerals. It is present in seawater, but sparingly, as the iodide ion, I−, to the extent of approximately 50 mg per metric ton (0.0016 ounce per ton) of seawater.

Introduction. Iodine is an antiseptic that kills bacteria and pathogens (Lawrence, 1998).
What does povidone iodine do to bacteria?
Povidone iodine has the broadest spectrum of antimicrobial activity of the available antiseptics, and has a rapid and persistent microbicidal effect. It is active against Gram-positive and -nega- tive bacteria, bacterial spores, fungi, protozoa and several viruses, including H1N1 influenza virus (swine flu).
How does iodine work as a disinfectant?
Iodine kills bacteria that can cause an infection. This type of iodine is for topical use only. When used as a disinfectant, iodine is often combined with another ingredient called povidone, and you might see it listed in a product’s ingredients as povidone-iodine.
Is Iodine a good sanitizer?
Iodine Sanitizers. Iodine sanitizers are effective against most microorganisms, including bacteria, yeasts, and molds at a usage level of 12.5 to 25 ppm. Unlike chlorine, iodophors are effective under a wide pH range (pH 2 to 10); however, they are primarily utilized under low-pH conditions (in the acidic range).
