The chemical properties of an atom depend on the number of what?

User Avatar

Asked by Wiki User

The chemical properties of an atom depend on the number of electrons in its outermost shell, known as the valence electrons. These electrons determine how atoms interact with other atoms to form chemical bonds.

No, a methyl group consists of a carbon atom bonded to three hydrogen atoms.

How many electrons are in argon- 38?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

Electrons can jump from one shell to another in an atom by absorbing or emitting energy in the form of photons. These transitions can occur even across forbidden zones under certain conditions, such as high energy input or external stimuli, resulting in electron movement between shells despite the energy level differences. This phenomenon is known as quantum tunneling.

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

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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

Are aluminum atoms different from silver atoms?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

An atom is a neutral particle consisting of protons, neutrons, and electrons. An ion is a charged particle that has gained or lost electrons, resulting in a net positive or negative charge. This structural difference arises from the presence or absence of electrons in the ion compared to the atom.

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

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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.

Does molecules contain elements?

User Avatar

Asked by Wiki User

Yes, molecules are composed of at least two or more atoms bonded together. These atoms can be the same element or different elements.

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

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

The Higgs boson is not the smallest particle. It is a fundamental particle that is responsible for giving mass to other particles in the universe. The smallest known particles are quarks and leptons, which are the building blocks of matter.
