The zinc ion +1 can exist but it is very rare and not likely to show up on school work but in your case it did how odd
Answer:
the discovery of atomic structure.
Explanation:
Rutherford was a famous scientist who gave his theory of atomic structure.
Ernest Rutherford was a great physicist who is well known for his pioneering studies and discoveries about atoms and radioactivity. Rutherford was considered to be the greatest experimentalist after Michael Faraday.
Rutherford's atomic model was one of the greatest discoveries which provided many answers and solutions to the structure of atom and molecules that our earth is surrounded of.
Rutheford discovered that an atom has a tiny mass of positively charged particles in the centre of the atom called nucleus and negatively charged electrons surrounds the nucleus.
Bohr joined Rutherford in his studies and discovered many new facts about the structure of the atom based on the Rutherford's model. Today atomic model is the product of Rutherford atomic structure.
<span>Na</span>₂<span>CO</span>₃<span> + 2 HCl = 2 NaCl + CO</span>₂<span> + H</span>₂<span>O
106 g Na</span>₂CO₃ -------- 2 x 36.5 g HCl
<span> x g Na</span>₂CO₃ ---------- 750 g HCl
<span>
Mass of Na</span>₂CO₃ = 750 x 106 / 2 x 36.5
<span>
Mass ( Na</span>₂CO₃) = 79500 / 73
<span>
Mass = 1089.04 g
Number of moles = 1089.04 / 106 => 10.27 mols of Na</span>₂CO₃

Answer:
6
8
6
Explanation:
Isotope given:
¹⁴₆C
In specie written as this;
Superscript = Mass number
Subscript = Atomic number
To find the protons, it is the same as the atomic number;
Protons = Atomic number = 6
Neutrons have no charges;
Neutrons = Mass number - Atomic number =
Neutrons = 14 - 6 = 8
The number of electrons is the same as the atomic number = 6
