sulfur - the extra neutron decays into a proton, electron and an electron-type antineutrino. Thus the unstable 15 proton, 17 neutron complement of P32 becomes the stable 16 proton, 16 neutron complement of sulfur. The emitted electron is the beta particle.

Is physics concerned with the study of atoms?

The study of atoms is one topic in physics, but by no means the only topic.


Why do gases do not connduct heat?

Conduction of heat is possible only in case of solids. In solids the atoms have been arranged in array forming lattice pattern. They are held up by metallic bonds. So heat conduction means the vibrational energy is transported from one atom or molecule to the other. But in case of fluids, ie both liquids and gases, there are no such bondage of atoms or molecules. So conduction is not possible, but convection becomes possible as the molecules or atoms they transfer the heat energy by transitory motion.


What do scientists use to measure the absolute age of a rock?

Finding the age of rocks based on the presence of naturally occurring long-lived radioactive isotopes of several elements in certain minerals and rocks.Many rocks and minerals contain radioactive atoms that decay spontaneously to form stable atoms of other elements. Under certain conditions these radiogenicdaughter atoms accumulate within the mineral crystals so that the ratio of the daughter atoms divided by the parent atoms increases with time. This ratio can be measured very accurately with a mass spectrometer, and is then used to calculate the age of the rock by means of an equation based on the law of radioactivity. The radioactive atoms used for dating rocks and minerals have very long half-lives, measured in billions of years. They occur in nature only because they decay very slowly. The pairs of parents and daughters used for dating are listed in the table.(see also the related link)The age of a rock may be determined by analysis of the matter it contains. Many minerals have radio active half lives that can be used to determine roughly how long ago the rock was formed. Another indication may be the type of fossils found in sedimentary rocks.


What is NO3 and NO4 stand for in chemistry?

NO3 means one nitrogen atom combined with 3 oxygen atoms to produce the nitrate ion. NO4 is one nitrogen atom combined with 4 oxygen atoms.


Why are nonbiodegradeable waste hazardous for mankind?

Because it may take many years.. or even centuries for the waste to decay. This means it could affect people living close by for a long time.

Why is uranium classified as a radioactive element?

That means that some of the atoms will decay over time.


Radioactive decay occurs when atoms of an unstable element?

It means that massive nuclei break apart.


What does it mean for an isotpe to be radioactive?

An isotope is radioactive if it undergoes spontaneous decay, emitting particles or radiation in the process. This decay results in the transformation of the atomic nucleus into a different element or a different isotope of the same element.


How does half life work in the context of radioactive decay?

In the context of radioactive decay, half-life is the time it takes for half of the radioactive atoms in a sample to decay. This means that after one half-life, half of the original radioactive atoms have decayed, and after two half-lives, three-quarters have decayed, and so on. The concept of half-life helps scientists understand the rate of decay of radioactive substances.


Is the percentage of radioactive atoms that decay during one half-life always the same?

Yes, the percentage of radioactive atoms that decay during one half-life is always the same, which is 50%. This means that half of the radioactive atoms present will undergo radioactive decay within each half-life duration.


What is the half lie of a radioisotope?

The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.


Explain how an atoms becomes an ion?

an ion is an atom with a posotive or negative charge. this means the atom gains or loses an electron


What does the composition of a substance does not change?

The composition of a substance remains constant if the chemical bonds that hold the atoms together are not broken. This means that the types and numbers of atoms present in the substance do not change, even if it undergoes physical changes like melting or boiling.


If you start with 60 atoms of uranium - 238 how many remain after 4470000000 years?

After 4.47 billion years, roughly half of the original atoms of uranium-238 would have decayed to lead-206 through alpha decay. This means there would be about 30 atoms of uranium-238 remaining.


What is decay.?

Decay means to rot or to become decomposed. For example: The tomato started to decay. Hope this helps!!


What is hybridization of central atoms in Bf3?

The central atom in BF3, boron, undergoes sp2 hybridization. This means that the 2s and two of the 2p orbitals of boron hybridize to form three sp2 hybrid orbitals, which are then used for bonding with the three fluorine atoms.
