Particle Physics

J.J. Thomson is credited with identifying electrons to have a negative charge through his experiments with cathode rays in the late 19th century.

You would get 18O, a stable nuclide with isospin 1.

Ernest Rutherford and James Chadwick were the scientists who discovered the subatomic particles that make up the nucleus. Rutherford discovered the positively charged protons, while Chadwick discovered the uncharged neutrons.

There are three unique chemical environments for the hydrogen atoms in pentan-2-ol as it has three different types of hydrogen atoms due to the presence of the hydroxyl group, alkyl chain, and the position of each hydrogen atom in the molecule. Each unique hydrogen atom will exhibit a distinct chemical shift in the proton NMR spectrum.

There are three unique chemical environments for the hydrogen atoms in propan-2-ol. This is because propan-2-ol has three different types of hydrogen atoms: the methyl group (-CH3) has three equivalent hydrogens, the methylene group (-CH2-) has two equivalent hydrogens, and the hydroxyl group (-OH) has one unique hydrogen.

Strontium-88 is an isotope of strontium that has 52 neutrons. It has an atomic number of 38, therefore the total number of neutrons (52) is obtained by subtracting the atomic number from the mass number.

A -2 anion indicates that the ion has gained two extra electrons. Since there are 8 protons in the nucleus (8 electrons in a neutral atom), adding two extra electrons would give a total of 10 electrons in the anion.

A single photon can only produce one electron in certain photoelectric interactions. This process involves the photon transferring all its energy to an electron, causing it to be ejected from an atom.

The number of valence electrons is the same number as the column of on the periodic table. Hydrogen has one, Calcium has two, etc. However, Helium may only have 2 and is an exception and Boron only wants 6 to fill its octet.

1. Proton: a particle from the atomic nucleus, positive charge, mass approx. 1 u.a.; discovered by Ernest Rutherford in 1919.

2. Neutron: a particle from the atomic nucleus, neutral, mass approx. 1 u.a.; discovered by James Chadwick in 1932.

3. Electron: a particle from the atom, negative charge, very low mass; discovered by

J. J. Thomson in 1932.

Scientists have accepted that the nucleus of the atom consists of neutrons and protons since the early 20th century, around the 1920s. This understanding was developed through experiments by scientists like Ernest Rutherford and James Chadwick.

There are 16 protons, 16 neutrons and 16 electrons in a Sulfur atom. *note it's atomic number- this is the number of protons in an atom of an element. There must be the same number of electrons to balance the charge. The atomic weight minus the number of protons gives you the number of neutrons

I think the answer is:

28 protons

28 electrons

34 neutrons

not 100% however.

Neutrons have been around since the beginning of the universe, no person created them.

Neutrons were first proposed to exist by Earnest Rutherford in 1920, but their existence wasn't verified until 1932 by James Chadwick.

Neutrons are used to bombard nuclei because they have no charge, allowing them to penetrate the nucleus and interact with its protons and neutrons. This can induce nuclear reactions, such as fission or fusion, leading to the production of new isotopes or releases of energy. Neutron bombardment is essential in nuclear reactors and accelerators for research purposes.

You probably mean to ask how a neuron transmits a signal. It would be extremely unusual for a neutron to transmit a signal. Neutrons can be detected by highly specialized devices, cloud chambers or bubble chambers, used by nuclear physicists.

Although protons don't "have electrons" themselves, one could say that an overall electrically neutral atom with 97 protons in its nucleus (Berkelium) would have also 97 electrons. More or less electrons would mean it's an ion and evidences a charge. Because of its electron configuration, Berkelium most commonly forms the +3 oxidation state (losing 3 electrons when forming a compound) but +2 and +4 are also known.

If one does the mathematics (which are *WAY* beyond the math level of even most scientists), one finds that string theory works only if one assumes the vibrations are aking place in eleven dimensions. Choose another assumption and the mathematics falls apart. Or, more exactly, the mathe eventually leads to falsehoods.

It is SOMETHING like this: if one assumes that there are ten dimensions in string theory, you end up with 1 = 0

Only if you assume that there are eleven dimensions does one get 1 = 1

One of most basic laws of science is the Law of the Conservation of Energy. It states that energy cannot be created or destroyed; it can only be changed from one form to another.

Kinda. There may or may not be smaller things inside the neutrons, protons and electrons, but yes protons neutrons and electrons are the only subatomics that have been proven to exist.

There are also the Strong Nuclear Force (which keeps protons from pushing each other away) and the Weak Nuclear Force which has something to do with quarks and W and Z bosons (which are inside protons neutrons and electrons). However these are forces and not particles.

Mass number is found by adding the number of protons plus the number of neutrons. Electrons are not added because they are so minute that their masses have almost no bearing on the total mass of the atom.

In this case, the mass number would be about 214.

No, Nickel has 2 electrons in its outermost shell! Look at the Periodical Table!!

Correction: The first answer was indeed correct. Ni = [Ar] 3d8 4s2 and if you count the number of valence electrons in each level, it comes up to ten. I just had a chemistry test on this, and I thought it was two at first too, but it's not. Don't think it's two unless you want to get the wrong answer.

I am not sure ,but the valency of nickel might be 2,but not according to periodic table,and who wrote this to look at periodic table?May be S/he has own periodic table in whick Nickel has 2 electrons in outermost shell.

This area is called the solar wind. It consists of charged particles, such as protons and electrons, that are emitted from the sun and flow outwards into space at high speeds.

Odor itself does not have weight because it is made up of volatile molecules that disperse into the air. When an object produces an odor, it does not lose weight in the process, as the molecules that create the smell come from the object's surface and do not affect its mass.

An assembly of protons and neutrons within an atom is called a nucleus. It is the central part of an atom that contains most of the mass of the atom and is positively charged due to the protons it contains.
