B. Flourine

Flourine has one of the highest ionization energies because it is so close to getting a full octet with eight atoms. It doesn't want to lose but rather gain an atom. On the periodic table, ionization energy increases as you head towards the top and to the right.

Answer:

The answer is F (Fluor)

Explanation:

The electrons are attracted to the nucleus and it is necessary to provide energy to remove them. Then the ionization energy is the energy needed to remove an electron to a neutral atom, gaseous and in a fundamental state.

By lowering in a group the ionization energy decreases because the electrons are increasingly distant from the nucleus and less attracted to it, which makes it easier to apply less energy to start the electrons from the atom.

In a period, the size of an atom decreases from left to right. So, the attraction generated by the nucleus on atoms is greater, and more energy is needed to tear them away. Then the ionization energy increases.

Taking all of the above into account, it can be said that the ionization energy increases from bottom to top and from right to left in the periodic table.

So, <u><em>the fluor (F) has the greatest first ionization energy.</em></u>

Explain the composition of dna nucleotides and the structure of the dna molecule need help
Kaylis [27]

A nucleotide is composed of a phosphate group, sugar, and nitrogen base. DNA is made of 2 strands of nucleotides linked together by covalent bonds between the phosphate and sugar of each nucleotide. The strands of nucleotides are linked together by hydrogen bonds creating DNA. Hope this helps and sorry if I made a mistake.

What did Josef Loschmidt and Amedeo Avogadro Contribute to our understanding of basic molecular numbers, sizes, and reaction rat
mario62 [17]

From Avogadro we obtained a physical constant of matter which is Avogadro's number, and from both scientists we understand that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.

<h3>What is Avogadro's number?</h3>

Avogadro's number, or Avogadro's constant, is the number of particles found in one mole of a substance.

The Avogadro's number is given as 6.02 x 10²³.

Summary of Josef Loschmidt and Amedeo Avogadro Contribution to chemistry.

  • Equal volumes of gas contain equal numbers of molecules,
  • Elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.

Thus, from Avogadro we obtained a physical constant of matter which is Avogadro's number, and from both scientists we understand that elementary gases such as hydrogen, nitrogen, and oxygen were composed of two atoms.

The equation, DF + heat Imported Asset D + F, is an example of an endothermic reaction.
zvonat [6]
The answer is TRUE.

If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.

Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.
