When potassium and fluorine bind what one will be the positive ion and which one will be the negative ion?

Potassium will be the the positive ion, and fluorine will be the negative ion because the potassium atom will give one electron to fluorine for they can both be stable. Fluorine will receive one electron from potassium and it will be stable because it has now 8 valence electrons. Giving is positive and receiving is negative. Hope this helps.

Potassium will become the positive ion (cation) because it loses one electron to form a stable octet, while fluorine will become the negative ion (anion) because it gains one electron to achieve a stable octet. This results in potassium having a +1 charge and fluorine having a -1 charge.

When potassium and fluorine bind which will form into a positive or negative ion?
When potassium and fluorine bind, potassium will form a positive ion (K+) and fluorine will form a negative ion (F-). Potassium will lose an electron to become a cation with a +1 charge, while fluorine will gain an electron to become an anion with a -1 charge.
How does EDTA effect potassium level?
EDTA can chelate or bind to potassium ions in the blood, forming a complex that reduces the amount of free potassium available for measurement in laboratory tests. This can lead to falsely low potassium levels in blood tests. It is important for healthcare providers to be aware of this interference when interpreting potassium levels in patients who are receiving EDTA therapy.
Why do polar covalent molecules have higher melting points than non polar covalent compounds?
They maintain their bonding far longer than nonpolar molecules can with the addition of heat energy. Remember their slightly negative ends will bind with the slightly positive ends of the adjacent molecule.
What results from hydrogen being at one end of a water molecule and oxygen at the other end?
They are not attracted to each other because one is polar and one is nonpolar.
What is a polar covalent bond?
A polar covalent bond occurs when two atoms share electrons unevenly due to differences in electronegativity. This results in a partial positive charge on one atom and a partial negative charge on the other, creating a dipole moment within the molecule.

Alloreactivity is a positive selection step or negative selection step?
Neither. Alloreactivity has to do with a lymphocytes reacting to a foreign antigen. Positive and negative selection are processes of central tolerance which is to say that they deal with a T cell's ability to bind self-antigen.
What is form ionic?
Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
Why gram positive bacteria typically more resistant that gram negative bacteria to antibiotics that disrupt plasma membranes such as polymyxin B?
Polymixin antibiotics interact with the lipopolysaccharide molecule of Gram negative bacteria. This component forms the outer leaflet of the outer membrane. Gram-positive bacteria do not have an outer membrane or lipopolysaccharide and thus polymixin antibiotics are unable to bind to the cell.

What is the difference between plain potassium pills and potassium gluconate pills?
In practicality, none. It is fairly simple chemistry. Potassim (K) typically does not just exist naturally as itself. It is usually is bonded with some other elements or substance. In the case of Potassium Pills, it is bonded with chloride and you get KCl. Potassium Gluconate just uses a a gluconate molecule instead of a Cl to bind it to. You may compare this to Na Cl or Sodium Chloride (Table Salt). You never eat sodium alone, it is always in combination with Chloride. The reason in short is that when Potassium is combined with another chemical it becomes charged positive (K+) and this is useful for your body. Any supplement you buy that contains Potassium, whether it be Potassium Gluconate or Potassium Chloride, are most often the same.
T cells undergo positive selection in the thymus which means?
T cell undergoes maturation in the thymus and one of the tests it must pass to mature into a single positive mature naive T cell is positive selection. In positive selection your body is making sure that the T cell that it produces is reactive to your own MHC. If it cannot bind to your own MHC, the T cell is useless and it will just die by neglect in your thymus. In positive selection the T cell is "tickled" with thymic endothelial cells that express your own MHC class 1 and MHC class 2. If there is an affinity of the T cell to bind to your MHCs it will continue to the next step in maturation which is negative selection. If the T cell binds way too strongly to your MHC it will also die. There is a specific range that it must bind to your own MHC for it to continue.
What is the action of iodine in grams stain?
Iodine is used to bind the Crystal Violet to the Gram Positive microbes.

How does ionization clean the air?
Ionization technology releases negative ions into the air, which attach to airborne particles such as dust, pollen, and bacteria. These particles become negatively charged and are then attracted to positively charged surfaces, effectively removing them from the air and reducing overall air pollution levels.
Is an allosteric site of an enzyme often involved in feed back inhibitition?
yes it can be. as the enzyme produces more of a product if that product becomes too many then one will bind to the allosteric site of the enzyme haulting its own production. (negative feedback). and the same thing can happen for positive feedback
