Explain how to draw the electron-dot diagram for oxygen.
AlexFokin [52]

The electron dot diagram for the oxygen atom shows six electrons around the symbol of the atom.

<h3>What is the electron dot diagram?</h3>

The electron dot diagram is the diagram of atoms of elements showing only the valence electrons present in the atom represented with dots.

The electron dot diagram for the oxygen atom is drawn as follows:

  • The number of valence electrons in oxygen atom is determined; valence electrons = 6
  • The symbol for the oxygen atom is written
  • The valence electrons are shown as dots around the symbol of the element.

In conclusion, the electron dot diagram uses dots around the symbol of an atom to show the valence electrons in the atom.

. A protein has molecular mass of 400 kDa when measured by size exclusion chromatography. When subjected to gel electrophoresis
8090 [49]

Answer:

The protein has 4 subunits: 2 subunits of 90 kDa, 1 subunit of 160 kDa and 1 subunit of 60 kDa

Explanation:

In gel electrophoresis, the SDS agent produces denaturation of the protein and confers negative charge, so the protein subunits can migrate according to their masses. It produces dissociation of the protein in its subunits but it cannot disrupt disulphyde bridges (S-S) that can bond subunits together.

From the data, with SDS we observe 3 bands ⇒ 180 kDa + 160 kDa + 60 kDa

The addition of dithiotreitol (DTT), a reducing agent, produces the disruption of disulphyde bridges. From the data:

With DTT ⇒ 160 kDa + 90 kDa + 60 kDa

We observe that 160 kDa and 60 kDa subunits are conserved (they are the same as with SDS only), but 180 kDa subunit is missing and in its place appears a band of 90 kDa - a half 180 kDa.

So, the band at 180 kDa is composed by two subunits bonded by a disulphyde bridge.

Therefore, the composition of the protein is: <em>1 subunit of 160 kDa, 2 subunits of 90 kDa and 1 subunit of 60 kDa</em>.

____33. When an atom undergoes gamma decay, the atomic number of the element
aleksandrvk [35]

Answer: Because only energy is emitted during gamma decay, the number of protons remains the same. Therefore, an atom does not become a different element during this type of decay. Q: The Figure below shows how helium-3 (He-3) decays by emitting a gamma particle.
