What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.
Radioactive elements include all those elements whose nuclei contain what?
Radioactive elements include all elements whose nuclei either:contain protons more than 83 proton, orcontain neutron to proton ratio out of the stability ratio.refer to related question below.
What is dangerously unstable and unpredictable?
Volcanoes can be dangerously unstable and unpredictable, with eruptions occurring suddenly and with little warning. The lava flows, ash plumes, pyroclastic flows, and gas emissions associated with volcanic activity can pose serious risks to nearby communities and the environment. Monitoring and forecasting volcanic activity is crucial for public safety.
Which object despite filling it up can't contain water?
A sieve or a colander cannot contain water because of the holes that allow liquid to pass through.
Why do objects have different mass?
Objects have different mass due to the amount of matter they contain. Mass is a measure of the total amount of material within an object, which can vary depending on factors such as size, density, and composition. Heavier objects have more mass because they contain more matter, while lighter objects have less mass because they contain less matter.
What atoms of the same element contain the same number?
Atoms of the same element must contain the same number of protons. This is because of the positive charge they provide.
What does band of stability for atomic nuclei refer to?
The band of stability contain stable isotopes.
Why do atoms combine to form bond?
Because they contain charged particles which attract each other
What does the band of stability for atomic nuclei refer to?
The band of stability is a way of viewing which isotopes of the elements are stable. If you make a graph of number of neutrons versus number of protons of the stable isotopes, you find that the stable isotopes make a thick curved line on the graph which is called the "band of stability." The lighter elements tend to have the number of neutrons equal to number of protons. The heavier elements tend to have more neutrons than protons. The band of stability can help you to predict the behavior of unstable radioactive isotopes as well, because you can predict which decay process will move the element closer to the "band of stability" so it will have the ideal ratio of neutrons to protons.
Why emulsions are thermodynamically unstable?
Emulsions are thermodynamically unstable because they contain two immiscible phases (e.g. oil and water) that tend to separate due to differences in interfacial tension between the phases. This separation is driven by the reduction in the free energy of the system, leading to coalescence and creaming of the emulsion over time.
What makes a nucleus unstable?
The strong nuclear force doesn't balance the electrostatic force.
Why are the fragments of fission radioactive?
Fission fragments are radioactive because they contain unstable isotopes produced during the nuclear fission process. These isotopes undergo radioactive decay, emitting radiation in the form of alpha, beta, or gamma particles to achieve a more stable state.
Chromosome 21 and 22 contain long stretches of repetitive DNA which?
do not code for proteins but are important for gene regulation and chromosome structure. These repetitive DNA sequences can vary in length among individuals and are associated with genetic disorders such as Down syndrome when present in abnormal amounts. They play a role in chromosomal organization and stability.
An element is determined by the number of?
An element can be identified by the number of protons in the nucleus of its atoms.
What is the simpest atom?
The simplest atom would arguable be hydrogen, containing just one proton and one electron. There are other hydrogen atoms, known as isotopes, all of which contain nuetrons. Hydrogen 1 is known as protium, or normal hydrogen. H-2 is dueterium with one proton, one nuetron and one electron. H-3 is tritium. Any isotopes above H-3 are highly unstable and exist for fractions of a second.
How many nuetrons are in the element oxygen?
There are 8 neutrons in oxygen element because the no. of electrons are equal to the number of protons and oxygen element contain 8 electrons.
What is a part of the nucleus?
Basically a nucleus is a mass of Baryons--protons and nuetrons (which are called nucleons jointly). Protons have a positive charge and nuetrons have no electric charge. One could also argue that a nucleus is made of quarks, the subatomic particles of which baryons are comprised.
