What is the monovalent radical that consists of two atoms?
The monovalent radical that consists of two atoms is the hydride ion (H-). It has a single negative charge and is composed of two hydrogen atoms.
Which term describes any substance that the body regards as foreign?
antigen
Can a receptor be an antigen?
No, they are entirely two different things. What might stimulate a receptor could be an antigen.
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
Naive antigen-nonspecific T cells do not become activated since they lack the T cell receptor specificity for the particular antigen being presented. They do not respond to IL-2 secreted by the activated antigen-specific T cells and remain in a resting state until they encounter an antigen to which they are specific.
Is T cell activation antigen specific?
Yes. The first signal that a T cell receives from an antigen presenting cell (dendritic cell) is MHC presenting an antigen (foreign peptide). This gives the T cell specificity to this antigen.
What are the specific charges of sodium and chloride?
Sodium is monovalent, the cation is Na+. Chlorine is monovalent, the anion is Cl-.
Is sodium chloride monovalent?
Sodium chloride is a compound and hasn't valence; sodium and chlorine, as elements are monovalent,
Is copper monovalent or divalent?
copper can form monovalent as well as divalent salts
What is charge on monovalent ion?
The charge on a monovalent ion is +1, meaning it has lost one electron and carries a positive charge. Examples of monovalent ions include sodium (Na+) and chloride (Cl-).
Are copper gold aluminum lithium have multiple valences?
Lithium is only monovalent. Aluminium is trivalent; rarely is bivalent or divalent. Gold is monovalent or trivalent.
What are monovalent metals?
Monovalent metals are metals that can form ions with a charge of +1. Examples of monovalent metals include lithium (Li), sodium (Na), and potassium (K). These metals typically lose one electron to achieve a stable electron configuration.
What is the molecule that can be recognized by the immune system?
Antigens.
What are the oxidation numbers for lithium?
+1. Lithium is monovalent.
Are monovalent electrons behaves like superconductors?
yes
Sodium ions are?
Na+ ions (monovalent +1)
What is antigen in German?
Abwehrstoff or Antigen
What does monovalent ion mean?
A monovalent ion is a cation that only has one valence electron to form an ionic bond with something else. Typically they are the alkali metals--Lithium, Sodium, Potassium, Rubidium, Caesium and Francium. Some transition metals can be found to be monovalent ions.
