Answer: Conclusion is that the cathode rays carries a negatively charged particle.

Explanation: The cathode ray tube experiment illustrates the discovery of electrons. This is due to the fact that beam of light bent towards the positively charged metal plate if put towards the glass tube. Since unlike particles attract it tells us that the beam carries a negative charge.

What are 1,2 and 3 examples of the same periodic table​
Serga [27]

Period

Group

Explanation:

On the periodic table the numbers 1,2 and 3 can represent either groups or periods.

The periodic table gives the arrangement of elements based on their atomic numbers

  • They are divided into vertical columns and horizontal rows
  • The vertical columns are the groups whereas the horizontal rows are the periods.
  • The vertical columns are made up of elements having the same number of electrons in their outermost shell.
  • The horizontal columns are made up of elements having the same number of shell.
  • On the periodic table, the groups are numbered 1 - 18
  • There are 7 periods on the table.

One reason spectroscopists study excited states is to gain information about the energies of orbitals that are unoccupied in an
Tanya [424]

Answer:

a) Mg

b) Cl

c) Mn

d) Ne

Explanation:

This electron configuration for the atom in its excited state violates the Aufbau principle or rule like we have above.

Aufbau principle states "that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels."

We however can know and identify which element is in the excited state by knowing the sum of the electron that spread across the orbital and matching it up with the atomic number of the element in the periodic table.

During strenuous exercise, the NADH formed in the glyceraldehyde 3-phosphate dehydrogenase reaction in skeletal muscle must be r
vekshin1

Answer:

The answer is pyruvate → lactate

Explanation:

In the reaction of glycolysis, glucose breaks down to form pyruvate yielding ATP and NADH.

Under or during strenuous exercise, which is an anaerobic condition, lactate is formed by the reoxidization of NADH and the conversion of pyruvate to lactate.
