Explanation:
The answer is the Calcium ion. It satisfies the conditions of the question.
Condition 1
The net ionic charge is one-tenth the nuclear charge.
In the Calcium ion, Ca²⁺. The nuclear charge in this ion is 20. The net ionic charge is 2.
2 / 20 = 1 / 10. So the net ionic charge is indeed one tenth of the nuclear charge.
Condition 2
The number of neutrons is four more than the number of electrons.
Mass Number of Ca²⁺ = 44
Atomic Number = 20
Neutrons = Mass Number - Atomic Number = 44 -20 = 24
Number of electrons = 20 - 2 = 18
Since Number of Neutrons = 22, Number of electrons = 18. This condition also holds.
As an ion and as an isotope = Ca²⁺, Ca - 42
Rules for naming ionic compounds with transition metal requires the elementary name of metal followed the anion name with suffix ide.
<h3>What are ionic compounds?</h3>
Ionic compounds are made up of ions, which are charged particles that occur when an atom (or group of atoms) acquires or loses electrons. Generally cations are metals and anions are non metals in it.
Following rules will be considered during naming:
- First determine the metal's elemental name.
- Give the nonmetal its elemental name and the suffix -ide.
- Use roman numerals to denote positive charge when naming metals that can have distinct oxidation states.
- Name the polyatomic ions according to their names.
Hence rules for naming are listed above.

Answer:
Bacterial genes contain no introns, so the cells, which lack splicing machinery, cannot express eukaryotic genes containing introns and exons. Mature eukaryotic mRNA, which has already been spliced, contains only exons, which, after they have been converted back to DNA, can be transcribed and translated by the bacteria.
Explanation:
This is thermodynamics. When you increase the temperature of an object, the particles gain on kinethic energy ergo the move faster. When you decrease it, they slow down.
