Explain specifically how an electron gives off light in an atom.
exis [7]

Answer:

Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.

Explanation:

When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital.

The tiny particles that make up elements are called atoms.<br> True<br> False
raketka [301]
True.
where the atom is the smallest (tiny) particle of an element, the atom may be neutral or ionized, and its size is around 100 picometers. The atom composed of a nucleus and one or more electrons (negative charge) bound to the nucleus, the nucleus contains protons (positive charge) and neutrons.

A sample of glucose, c6h12o6, contains 2.03 x 10^21 atoms of carbon how many atoms of hydrogen does it contain?
kirza4 [7]

Given the data from the question, the sample of the glucose contain 6.04×10²¹ atoms of hydrogen

<h3>Avogadro's hypothesis </h3>

1 mole of substance = 6.02×10²³ atoms

<h3>How to determine the number of hydrogen atoms in the glucose</h3>

From the formula of glucose, C₆H₁₂O₆, we can see that the mole ratio of carbon to hydrogen is:

  • Mole of carbon = 6 moles
  • Hydrogen = 12 moles

Ratio = carbon / hyddrogen

Ratio = 6 / 12

Thus, for every 6 moles of carbon, there are 12 moles of hydrogen.

Thus, we can determine the number of atoms of hydrogen present in the compound as follow:

6 moles of carbon = 12 moles of hydrogen.

Therefore,

3.02×10²¹ atoms of carbon = (3.02×10²¹ × 12) / 6

3.02×10²¹ atoms of carbon = 6.04×10²¹ atoms of hydrogen

Thus, the number of atoms of hydrogen present in the compound is 6.04×10²¹ atoms
