When radioactive phosphorus decay it emits a positron will the resulting nucleus be another isotope of phosphorus?

No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but Atomic Mass remains the same so phosphorus is converted into silicon atom with same atomic mass.

What is the correct electron configuration of phosphorus?
Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3. Another way to write that is [Ne] 3s2 3p3. The [Ne] represents the fact that the beginning of phosphorus' electron configuration is the same as Neon's.
What elements are radioactive?
Answerelements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. AnswerAll elements have radioactive isotopes.There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...Here is the whole list: http://periodictable.com/Elements/Radioactive
An element that decays to another element over a period of time is?
A property of that element. An unstable element. A radioactive element
Change of one element into another is called what?
transmutation, neutrons
What kind of reaction can change one element into another?
There are only 2 ways that can happen, fission or fusion. Fusion is when two atoms combine to become a larger atom (almost exclusively two hydrogen atoms becoming 1 helium atom). Fission is much more common and is present in all radioactive elements.
What is the antiparticle of a positron?
Since the positron is the antiparticle of the electron, it follows that the electron is the antiparticle of the positron.
What is an antielectron?
An antielectron is another name for a positron.
What is the breakdown of a radioactive isotope of the same element or of another element?
radioactive decay
How do radioisotopes of an element differ feom other isotopes?
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.
What is another name for a box of phosphorus and sulfur?
matches
If a substance is radioactive is its compound radioactive?
Yes. A radioactive atom is a radioactive atom. If that atom exists as a single atom and is uncombined and it is radioactive, it's radioactive. If that same atom is chemically combined with another or other atoms, it's still radioactive. It's just that simple.
What happens when a radioactive isotope decays?
It emits an electron and an antineutrino and increases by one in atomic number while ending up with one fewer neutrons, or it emits a positron and a neutrino and decreases by one in atomic number while ending up with one more neutron. In both cases the total number of protons and neutrons remains unchanged, and the number of orbital electrons will eventually change to match the new atomic number.
What happens directly after ATP is used up?
You make ATP after you "break" the phosphorus group off and produce ADP. You can add another phosphorus group to ADP producing then another ATP.
What isotope is formed when 28P emits a positron?
In this reaction we see an isotope of phosphorus,28P, undergo beta plus decay. In beta plus decay, a proton in the nucleus of an atom undergoes a transformation wherein an up quark becomes a down quark. This event, mediated by the weak nuclear force (or weak interaction), results in the proton becoming a neutron. When this happens, the atom changes from one element to another element in a process called transmutation. Here we see phosphorus become silicon, and the equation might look like this: 1528P => 1428Si + e+ + ve In this beta plus decay event, we see the phosphorus-28 atom transforming into a silicon-28 atom, and we see the positron (e+) and the neutrino (ve) kicked out of the nucleus on the back side of the event. Some links are provided below for extra investigation.
Radioactive decay occurs when?
When a radioactive element slowly turns into another element/s when it emits various particles.
What is another name for radioactive dating?
Carbon Dating
Other name for phosphorus?
I don't believe there is another name for Phosphorus, but it can be spelled: PhosphorousActually, phosphorus and phosphorous are different things. Phosphorous is the adjectival form of P3+ valence, like how sulfur forms sulfurous and sulfuric compounds, its the same with phosphorus. It forms phosphorous compounds.
