A bond in which atoms share electrons is called a?

The type of bond in which two atoms share electrons is called a covalent bond.

Does methyl group consists of a carbon bonded to three hydrogen atoms?

Yes, a methyl group consists of three hydrogen atoms bonded to a carbon atom, with a univalent radical.

Add one hydrogen atom and you have methane.

How many electrons are in argon- 38?

Argon-38 is a specific isotope of argon, and it has 18 electrons since the number of electrons in an element is determined by its atomic number.

How electrons are jumping from one shell to other in the presence of forbidden zone of an atom?

may be electrons disappear from one shell when it receives it maximum energy and reappear at the other shell.

or

when the electrons receives it maximum energy it may convert into another form in band gap of an atom and again converted into its original form when it come it another shell which has fixed amount of energy...

How many protons neutrons and electrons are in technetium-99?

Technetium has 43 protons, 43 electrons (in the neutral atom), and a differing number of neutrons depending on which isotope of the element is being considered. There are no stable isotopes of technetium, and it's discovery was a long time coming, though it had been predicted to exist by none other than Mendeleev himself.

The longest lived isotopes (many thousand years half-lives) have 54, 55, and 56 neutrons, and isotopes have been recorded with from 42 to 75 neutrons. Other than the three isotopes mentioned, the isotopes of technetium have half-lives measured in days to seconds to small fractions of a second. Outside 97Tc, 98Tc and 99Tc, none of the atoms of this synthetic transition metal hang around long.

What is the difference between GeV and MeV electron bolts?

GeV (gigaelectronvolt) and MeV (megaelectronvolt) are units of energy used to describe particle energies. 1 GeV is equal to 1000 MeV. Therefore, GeV electrons have higher energy than MeV electrons. These units are commonly used in particle physics to describe the energy of subatomic particles.

What are atoms with the same atomic number and same chemical properties in their purest form?

Atoms with the same atomic number and same chemical properties in their purest form are isotopes. Isotopes have the same number of protons and electrons but different number of neutrons. This does not affect their chemical behavior but may affect physical properties like atomic mass.

How many carbon atoms in a hope diamond of 44.4 carrots?

A carrot? Well I'll assume you mean carat.

A carat is unit of mass used by the diamond trade.

1 carat is 200mg.

44.4 carats is therefore 8.8 grams

Diamonds are pure carbon. Avogadros number tells us ho many atoms are in a gram atom of carbon

this is 6.023x1023 atoms in 12.011 grams of carbon

therefore there are (6.023/12.011) X 8.8 X 1023 atoms

I make that 4.41 x 1023 atoms

What species contain 16 neutrons?

An element with 16 neutrons could be oxygen-16, which is a stable isotope of oxygen.

Are aluminum atoms different from silver atoms?

Yes, aluminum and silver atoms are different elements with distinct properties. Aluminum has an atomic number of 13 and a silvery appearance, while silver has an atomic number of 47 and is known for its lustrous, metallic appearance. Their chemical and physical properties vary due to their unique atomic structures.

What charge is the nuclease in an atom?

The nucleus in an atom carries a positive charge due to the presence of protons. Electrons, which carry a negative charge, orbit around the nucleus.

What does the atomic number of an elemnet represent?

The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It determines the identity of the element on the periodic table and distinguishes it from other elements.

What structurally different between an atom and an ion?

Atoms are neutral species containing protons and neutrons in the nucleus and electrons in the orbitals (or shells).

Ions are formed when an atom gains or loses electrons.

If an atom gains electrons, then negatively charged ions called anions are formed.

If an atom loses electrons, then positively charged ions called cations are formed.

Find the density of the nucleus of an iron atom with a radius of 3.555Fm and an atomic mass of 56?

To find the density of the nucleus, we first need to calculate the volume of the nucleus. The volume of a sphere is given by V = 4/3 * π * r^3, where r is the radius of the nucleus. Once we have the volume, we can divide the mass of the nucleus (which is equal to the atomic mass) by the volume to find the density. Density = mass / volume. Substituting the given values, we can calculate the density accordingly.

How many protons in carbon 6?

There are 6 protons in a carbon-6 atom. The number 6 in the atomic symbol (C-6) represents the atomic number, which equals the number of protons in the nucleus of a carbon atom.

Is the charge of a nucleus positive negative or zero The charge of an atom?

The charge of a nucleus is positive, as it contains protons which have a positive charge. The charge of an atom overall is neutral, as the number of protons (positive charge) is equal to the number of electrons (negative charge) in a neutral atom.

Who stated that there were two types of electric charge positive and negative?

Benjamin Franklin. The very famous scientist who did experiments with flying kites during lightning and declared that lightning is due to the electrical discharge between oppositely charged clouds.

What group would 1s2 2s2 2p6 3s2 3p6 3d1 4s2 belong to?

This electron configuration belongs to the element Potassium, which is in group 1 of the periodic table.

Does molecules contain elements?

The simple answer is yes. A molecule is made up of elemental atoms. For example, a water molecule is made up of two hydrogen atoms bonded to an oxygen atom

What bond both atoms exert the same pull on shared electrons?

A nonpolar covalent bond forms when two atoms share electrons equally because they have the same electronegativity. In this bond, there is no attraction difference between the two atoms, and they pull on the shared electrons with equal strength.

Is the Higgs-Boson the smallest particle?

  1. On 4 July 2012, the ATLAS and CMS experiments at CERN's Large Hadron Collider announced they had each observed a new particle in the mass region around 126 GeV. This particle is consistent with the Higgs boson predicted by the Standard Model.
  2. Well this is what the LHC is telling us. However it could be wrong, for example maybe it wasn't the Higgs, maybe it was a new particle. This all just mostly based on calculations by maths. The mass was predicted by maths. Then the LHC rounded it up and ended the search for the great God Particle.

What is canunda shell?

The canunda shell is a large marine snail shell that originates from the Canunda National Park in Australia. It is prized for its intricate and unique design, making it a sought-after collectible item by shell enthusiasts and collectors alike.

How do yo find an atoms mass number?

The mass number of an atom is determined by adding together the number of protons and neutrons in the nucleus of the atom. This information can be found on the periodic table of elements where the mass number is typically listed underneath the symbol of the element.

How many uranium atoms are in 6g of pure uranium?

To find the number of uranium atoms in 6g of pure uranium, we first need to calculate the molar mass of uranium, which is approximately 238.03 g/mol. Then, we use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the mass to number of atoms. So, 6g of uranium contains about 6.022 × 10^23 atoms.
