What is a pure substance that is made of only one kind of atom?

A pure substance made of only one kind of atom is called an element. Elements are the simplest form of matter and cannot be broken down into simpler substances by chemical means. Each element is represented by a unique chemical symbol, such as "H" for hydrogen or "O" for oxygen, based on its atomic structure. Examples of elements include hydrogen, oxygen, carbon, and gold.

What is the size of proton in nm?

Oh, dude, the size of a proton is about 0.87 femtometers, which is like super tiny. It's like trying to find a grain of sand on a beach, but with way more math involved. So yeah, it's like really, really small.

What is the correct Lewis structure for FSiN?

Alright, buckle up buttercup. The correct Lewis structure for FSiN is where fluorine (F) is single bonded to silicon (Si), silicon (Si) is double bonded to nitrogen (N), and nitrogen (N) is single bonded to fluorine (F). Make sure those octets are happy and everyone has their dancing shoes on.

How many energy levels does radium have?

Radium, a radioactive element with atomic number 88, has 7 energy levels. These energy levels correspond to the possible orbits of its electrons around the nucleus. The electrons in radium fill these energy levels according to the Aufbau principle, Pauli exclusion principle, and Hund's rule. Each energy level can accommodate a specific number of electrons based on the formula 2n^2, where n represents the principal quantum number of the energy level.

How many protons and electrons in H3O?

Well, honey, in the H3O+ ion, there are 3 hydrogen atoms, each bringing 1 proton and 1 electron to the party. So that's 3 protons and 3 electrons from the hydrogen atoms. Then you've got 1 oxygen atom, with 8 protons and 8 electrons. Add it all up, and you've got a total of 11 protons and 11 electrons in the H3O+ ion.

How do you draw two isotopes of carbon and give the mass number for each?

To draw two isotopes of carbon, you would start with the atomic symbol "C" in the center of a circle. For carbon-12, which has a mass number of 12, you would write "12" as a superscript before the atomic symbol "C." For carbon-14, with a mass number of 14, you would similarly write "14" as a superscript before the atomic symbol "C." This notation helps differentiate between the isotopes based on their respective mass numbers.

What element have 3 energy levels?

Ah, what a lovely question. Elements with 3 energy levels are like a beautiful painting with three layers of colors. You see, elements like lithium and sodium have 3 energy levels where their electrons dance around, creating harmony and balance in the world of chemistry. Just imagine these elements as little artists, each playing their part in creating the masterpiece of life.

How many oxygen atoms are in copper sulfate Cu2(SO4)3?

In one molecule of copper sulfate, Cu2(SO4)3, there are a total of 12 oxygen atoms. This can be calculated by breaking down the compound into its individual atoms: 3 sulfur atoms and 12 oxygen atoms from the sulfate ions, and 2 copper atoms. Therefore, the total number of oxygen atoms in one molecule of copper sulfate is 12.

How many hydrogen atoms are present in 25.6g of Urea?

Does nuetron proton and electron have to be capitalized?

Oh, what a lovely question! You see, when we talk about specific particles like neutrons, protons, and electrons, it's not necessary to capitalize them unless they are at the beginning of a sentence. Just let them flow on the canvas of your words, whether big or small, they all play an important role in creating the beautiful masterpiece of science.

How many atoms are in diatomic molecules?

Two atoms are contained a single diatomic molecule. Elemental Hydrogen is an example of this where two hydrogen atoms share their only electrons in a single covalent bond.

The process in which atoms are rearranged and chemical bonds are broken and formed to produce a chemical change of a substance.?

The process you are describing is called a chemical reaction. This involves the breaking and forming of chemical bonds between atoms to result in the transformation of one or more substances into different substances with new properties.

How many valence electrons do stable atoms have?

A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)

What element has 12 electrons 12 protons and 14 neutrons?

This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.

What happens to a neutron atom if it gains or loses electrons?

Neutrons are neutral subatomic particles in the nuclei of atoms. To remove neutrons from an atom would take an act of nuclear fission.

Neutrons are about as heavy as protons. The gain of a neutron would make the atom heavier; the loss, lighter. The gain or loss of neutrons will not affect the charge of an atom.

What group would an element with 120 protons and 2 electrons go in?

An element with 120 protons and 2 electrons would belong to Group 2 on the periodic table, also known as the alkaline earth metals group. Elements in this group typically have 2 valence electrons and exhibit similar chemical properties due to their electronic configuration. Examples of elements in Group 2 include beryllium, magnesium, calcium, strontium, and barium.

What is the nuclear equation of nitrogen 13 undergoes beta decay?

Here's your equation for the beta minus decay of carbon-14: 614C => 714N + e- + ve An atom of carbon-14 transforms into an atom of nitrogen-14 here. In carbon-14, a down quark in a neurton becomes an up quark. This change, mediated by the weak interaction or weak force, changes that neutron into a proton. This creates another element, the nitrogen, and an electron is created within the nucleus and then is ejected along with an antineutrion. Use the link below to learn more about beta decay.

How many atoms are in 3n2?

6. When a formula contains no parentheses and only one kind of atom, the total number of atoms equals the product of the subscript and the coefficient.

What -2 charge ion has same electron configuration as krypton?

The -2 charge ion with the same electron configuration as krypton is the oxide ion (O2-). Krypton has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. The oxide ion gains two electrons to achieve a full valence shell, resulting in an electron configuration of 1s2 2s2 2p6.

How many atoms are in a molecule of borax Na2B4O7?

13 atoms are in one molecule of borax but that is surrounded by 10 water of hydration molecules containing 3 atoms each; giving a total of 43 atoms altogether in and around one borax molecule.

Would the same behavior exist in atomic radius for the ions of atoms?

No, the behavior of atomic radius for ions of atoms would not be the same. When an atom gains or loses electrons to become an ion, its radius changes. Cations (positively charged ions) are smaller in radius compared to their parent atoms because they lose electrons, leading to increased effective nuclear charge pulling the remaining electrons closer. Anions (negatively charged ions) are larger in radius as they gain electrons, resulting in increased electron-electron repulsion and expansion of the electron cloud.
