Which atom contains exactly 15 protons
Which atom contains exactly 15 neutrons?
Therefore the isotope with 14 protons and 15 neutrons is Silicon-29.
Which molecule has only 15 protons?
This is the isotope phosphorus-31. It has 15 protons, 15 electrons, and 16 neutrons.
What atom has exactly 15 electrons?
phosphorus
Explanation: if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
What will an atom with 15 protons do?
The positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons. The atoms can lose or gain an electron to form ions. For a neutral atom with 15 protons, the number of electrons is 15.
Which atom contains exactly 16 protons?
(b) By referring to a periodic table or a table of elements, we see that sulfur (S) has an atomic number of 16. Thus, each atom or ion of sulfur must contain 16 protons.

What element has 15 protons and 17 neutrons?
Phosphorus 32
Phosphorus 32 (P-32) is the phosphorus isotope whose nucleus consists of 15 protons and 17 neutrons. It disintegrates by emitting a β- (1.71 MeV) particle in 32S with a half-life of 14.263 days. It is an artificial radioactive substance obtained by neutron bombardment of stable phosphorus.
Who discovered phosphorus-32?
Hevesy
Hevesy was the first investigator to use 32P in biological research. His first publication using 32P, in 1935, was entitled “Radioactive indicators in the study of phosphorus metabolism in rats” [3].

Where is phosphorus-32 found?
It is embedded in nucleic acids involved in all metabolic processes of living bodies and replaces stable phosphorus-31. As phosphorus-32 is a beta emitter, its movement within the body can be tracked using tomography.
What is Nickel 63 used for?
Nickel-63 has a low energy beta spectrum and reasonably long half-life, making it useful as an alternative for tritium in some applications. Major use is in gas chromatograph sources where the greater stability of electroplated radionickel compared to metaltritides makes it of particular value.
What is the symbol of phosphorus?
phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
What is IR 192 used for?
What is it used for? Ir-192 is used in industrial gauges that inspect welding seams and in medicine to treat certain cancers. Where does it come from? Ir-192 is a manmade radioactive element that is formed from nonradioactive iridium metal in a nuclear reactor.
