Answer:
- <em>There are </em><u><em>14 protons</em></u><em> (Z) and </em>14 neutrons<em> (N) in a nucleus of the most common isotope of silicton.</em>
Explanation:
The notation of the <em>most common isotope of silicon</em> is:
The superscript, 28, to the left of the chemical symbol, Si, is the mass number, usually identified with the symbol A, and it is the sum of the protons and neutrons.
The subscript, 14, to the left of the chemical symbolr, Si, is the atomic number, Z, which is the number of protons.
Then, you have this equation:
- mass number = number of protons + neutrons, or, in symbols:
The number of protons is the same for any isotope of the same element. This is, all the isotopic forms of silicon have the same number of prtons: 14
The number of neutrons is determined from the equation A = Z + N, solving for N:
- N = A - Z = 28 - 14 = 14.
Hence, the most common isotope of silicon has 14 protons and 14 neutrons.
Answer:
They increases the distance of applied force(torque)as well as they change the strenght or direction of a force(90 angle work).

Answer:
The star is a special star
Explanation:
it is a binary star it is dominated by a luminous main sequence of star! it has a magnitude of -1.46. Sirius A's apparent bright ness can be attributed both to its inherited luminosity! 20 times that of thr sun anf its proximity. At just 8.7 Light years away sirius is the seventh closest star to earth.
Sulfur is an element in the periodic table that has a chemical symbol of S. This element is the 16th element in periodic table. This means that the atomic number or number of protons in the nucleus of the atom is equal to 16.
The number following the name of the element is the mass number. The following are the complete symbol that are arranged as follows:
chemical symbol - atomic number - mass number
*Sulfur-32
S - 16 - 32
*Sulfur-33
S - 16 - 33
*Sulfur-34
S - 16 - 34
