sulphur has 6 v.e

f has 7 each

so total 34 v.e

sf4 has a trigonbal bipyramidal structure.

it has 1 lone pair of electrons too. "which do not enter into bonding

sf6 is possible too.

actually...

a trgonal byprimidal is a structure with 5 electron groups (Bonding electrons + lone pair electrons). SF4 only has 4 electron groups around it,(all valnce electrons bonded with fluorine and no lone pairs) so it is actually has a tetrahedral geometry. sp^3.

A neutron is a subatomic particle found in the nucleus of an atom that has zero charge. It plays a crucial role in providing stability to the nucleus by balancing the repulsive forces between positively charged protons.

Br has an atomic number of 35 giving it 35 protons. Since it has a charge of 1- it will have 36 electrons to form a octet.
Br- will have 35 protons and 36 electrons. The negative charge indicates it gained an electron.

There are quarks in the nucleus of an atom, but they are found there because quarks make up protons and neutrons which make up atomic nuclei. They (quarks) do not have "individual identities" in the nucleus of an atom, but are elementary particles that are the building blocks of composite particles called hadrons. Quarks are never found in isolation anywhere.

Electrons have the least amount of energy compared to protons and neutrons. Protons and neutrons have similar amounts of energy in an atom, as they are found in the nucleus and contribute to the majority of the atom's mass.

Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope.

Number of neutrons in a calcium atom = Mass number - 20

Electrons do radiate energy when they are accelerated, but in stable orbits around an atomic nucleus, they do not radiate energy due to a balance between the centripetal force keeping them in orbit and the electromagnetic force. This results in a stable orbit without energy loss.

The "fermion sign problem" refers to a computational challenge in quantum many-body problems when simulating systems of fermions using Monte Carlo methods. As fermions follow the Pauli exclusion principle, the wavefunction must be antisymmetric under particle exchange. This can lead to an exponentially growing number of configurations needed to accurately simulate the system, making calculations computationally demanding or impractical.

They go into photosystem I.

John Dalton believed that atoms were the fundamental building blocks of matter, and that they could not be created, destroyed or split. However he was wrong, because atoms are made out of subatomic particles such as Protons, Neutrons and Electrons - and later still, it was discovered Protons and Neutrons too are made of even smaller particles.

From energy in photons

H+ has 1 proton and 0 electrons.

Normal hydrogen has 1 proton and 1 electron. The number of protons always remains the same. The negative electron and the positive proton balance out the charge so that normal elemental hydrogen is neutral.

H+ is the oxidized form of hydrogen. Its electron was taken away, so now it's left with 1 proton and 0 electrons, making its charge positive.

H- is the reduced form of hydrogen. It has gained an electron, so now it has 1 positive proton and 2 negative electrons, making the charge equal to negative 1.

The energized electrons in photosynthesis come from water molecules that are split during the light-dependent reactions. These electrons are transferred through a series of protein complexes in the thylakoid membrane, creating a proton gradient that drives ATP synthesis.

235 (mass number) - 92 (number of protons) = 143 (number of neutrons)

actually total energy is the sum of potential energy and kinetic energy....potential energy= -2*kinetic energy . By using this relation you will get that sum of potential and kinetic energy is equal to the magnitude of kinetic energy and it is less than zero...hope this will be enough for you....

Tin can act as both an electron donor and an electron acceptor, depending on the chemical reaction it is involved in. In some reactions, tin can donate electrons to other elements, while in others, it can accept electrons.

A neutron trigger is used in nuclear fission reactions to initiate the splitting of atomic nuclei. By emitting neutrons, the trigger can start a chain reaction in which other nuclei are split, releasing more neutrons and energy. This process is fundamental to the operation of nuclear reactors and nuclear weapons.

It is useful in the diagnosis, staging, and treatment of cancer because it provides information that cannot be obtained by other techniques such as computed tomography and magnetic resonance imaging.

Non-metals have a set amount of electrons, though metals have a sea of electrons; this means that metals can have a normal variety of charges to choose from. Some extra electrons may go to the non-metal, though I'm not sure about the increase in size.

Regardless of the isotope, every silicon atom has 14 electrons.

Proton pump inhibitors (PPIs) can interact with other medications, affecting their absorption and metabolism. Common interactions include reduced effectiveness of clopidogrel, increased risk of hypomagnesemia with diuretics, and increased levels of certain drugs metabolized by the liver due to PPI effects on liver enzymes. It is important to consult a healthcare provider before starting or stopping any medications while taking PPIs.

In a Bohr model, the maximum number of electrons that can exist on each energy level is determined by the formula 2n^2, where n is the principal quantum number. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second level (n=2) can hold a maximum of 8 electrons, and so on.

First you would calculate the number of protons...

the number of protons = the total mass number

then the number of protons should = the nummber of electrons(unless their is a number in front of the element like +1)

therefore= # of protons = # of electrons

Protons are similar to hydrogen ions because they are positively charged particles found in the nucleus of an atom. Hydrogen ions are just protons that are not associated with an electron.

An electron gun is a device that emits a focused beam of electrons. It is commonly used in cathode ray tubes (CRT) in TVs and computer monitors to generate images by directing the electron beam onto a phosphor-coated screen, causing it to light up and produce images.
