Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all.

The atom is the smallest unit of an element that maintains the properties of that element. All atoms are composed of subatomic particles called neutrons (particles with no charge, neutral), electrons (negatively charged particles) and protons (positively charged particles).

The proton is located in the nucleus, an atom's central region. The number of protons in the nucleus is the atomic number, which determines the identity of an element. The neutron is located in the nucleus of an atom. Together, the total number of protons and neutrons in the nucleus determine the mass number of the atom.

The electron is likely to be found in the electron cloud, a region around the nucleus of an atom. The electrons located in the electron cloud interact with other atoms or ions when joining together to create a compound. A compound a substance made up of atoms or ions of two or more different elements joined by chemical bonds.

Hope that helps.

Covalent bonds are formed when 2 neutral atoms come together to share a pair of electrons, where each atom contributes one electron each to be shared.

The covalent bond is kept together by the electrostatic attraction between the nuclei of the atoms and the shared pair of electrons.

Covalent bonds are usually formed between non metals with a small difference in their electro negativity.

the correct answer is

A. Neutral atoms coming together to share electrons

What is conductivity? How is it measured?

horrorfan [7]

Conductivity is a measurement of the ability of an aqueous solution to transfer an electrical current.

Explanation:

To calculate the conductivity of a solution you simply multiply the concentration of each ion in solution by its molar conductivity and charge then add these values for all ions in solution.

Be sure to answer all parts. Nitric oxide, NO·, is a radical thought to cause ozone destruction by a mechanism similar to that o

SIZIF [17.4K]

Answer:

See image attached and explanation

Explanation:

The stratospheric ozone layer is very important in absorbing high-energy ultraviolet radiation that is harmful to living systems on earth. The concentration of ozone in the stratosphere is determined by both thermal and photochemical pathways for its decomposition. Nitric oxide, NO, is a trace constituent in the stratosphere that reacts with ozone to form nitrogen dioxide, NO2, and the diatomic oxygen molecule. The nitrogen-oxygen bond in NO2 is relatively weak. When an NO2 molecule encounters an oxygen atom, it transfers an oxygen, forming O2 and NO. The chemical reactions involved are formations of NO2 following by reaction of NO2 with atomic oxygen for form NO and O2. The sum of both reactions show that the overall reaction is simply the reaction of ozone with atomic oxygen to form two molecules of molecular oxygen. Hence, NO only serves as a catalyst, it does not undergo a permanent change itself.
