Answer:
B. six protons, six neutrons, and six electrons
Explanation:
Carbon-14 and Carbon-12 are the isotopes of carbon.
Isotope:
An atom of an element that contain same atomic number but different atomic mass.
The difference in atomic mass is due to the different number of neutrons present, but the number protons and electrons are remain same.
In C-14 there are six protons and six electrons while number of neutrons are,
Mass number - number of protons = number of neutrons
14- 6 = 8
In C-12 there are six protons and six electrons while number of neutrons are,
Mass number - number of protons = number of neutrons
12- 6 = 6
Thus in C-12, there are six protons, six neutrons and six electrons present.
Emissions are substances that are emitted; in an energy sense, these are most often waste products of a process aimed at obtaining useful work. The most common emissions from energy are associated with the generation of electricity and the transportation of people and goods.
<h3>How is energy emitted?</h3>
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
<h3>What is the energy of the emitted photons?</h3>
A photon can be emitted when an excited electron falls from a higher energy level to a lower level. The energy of the emitted photon will be equal to the energy drop. The energy of an electron and corresponding photon (emitted or absorbed) is expressed in electron- volts (eV's).

Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
Explanation:
The interatomic and the intermolecular. Interatomic Unions: They are those that are established between the atoms. There are three types. In two of them, the so-called Ionic and Covalent, the atoms try to

Las interatómicas y las intermoleculares. Uniones Interatómicas: Son las que se establecen entre los átomos. Hay de tres tipos. En dos de ellas, las llamadas Iónicas y Covalentes, los átomos tratan de llegar a completar el último nivel con ocho electrones cumpliendo con la clásica teoría del octeto de Lewis.
