(F) Na2O  ionic bond.

<h3>What are a covalent compound and ionic bond?</h3>

Covalent bonds form when two or more additional nonmetals combine. For instance, both hydrogen and oxygen are nonmetals, and when they connect to make moisture, they do so by forming covalent bonds. Combinations that are composed of only non-metals or semi-metals with non-metals will demonstrate covalent bonding and will be classified as molecular combinations.

  • As a broad rule of thumb, combinations that involve a metal binding with either a non-metal or a semi-metal will show ionic bonding. Therefore, the compound created from sodium and chlorine will be ionic (a metal and a non-metal). Nitrogen monoxide (NO) will be a covalently bound molecule (two non-metals), silicon dioxide (SiO2) will be a covalently bound molecule (a semi-metal and a non-metal) and MgCl2 will be ionic (a metal and a non-metal).
  • A polyatomic ion is an ion comprised of two or more particles that have a commission as a group (poly = many). The ammonium ion (see figure below) consists of one nitrogen atom and four hydrogen atoms. Concurrently, they constitute a single ion with a 1+ charge and a formula of NH4+. The carbonate ion (see figure below) consists of one carbon particle and three oxygen atoms and maintains a comprehensive charge of 2−. The procedure of the carbonate ion is CO32−.

discuss the origin of the line citing the bohr theory of the atom specify any energy transitions that are applicable
xeze [42]

Answer:

Niels Bohr states that the line spectrum of the hydrogen atom by assuming that the electron revolve in circular paths and that the paths  have an allowable radii. ...

Explanation:

discuss the origin of the line citing the bohr theory of the atom specify any energy transitions that are applicable

Niels Bohr states that the line spectrum of the hydrogen atom by assuming that the electron revolve in circular orbits and that orbits have an allowable radii. ... an absorption spectrum is produced, dark lines in the same position as the bright lines in the emission spectrum of an element are produced.

Bohr Atomic Model. Bohr Atomic Model : In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. ... The atom will be stable in the state with the smallest orbit

Bohr explains to us that electron revolve round the nuclues of an atom and possess energy levels. they can change energy levels
