A) Since both are carbons with the only difference in the number of neutrons,
They are called Isotopes
B) Carbon - 12 has 6 protons and 6 neutrons, while Carbon-13 has 6 protons and 7 neutrons,
Therefore Carbon-12 and Carbon-13 have the same number of protons
C) Carbon - 12 has 6 protons and 6 neutrons, while Carbon-13 has 6 protons and 7 neutrons,
Therefore Carbon-12 and Carbon-13 has different numbers of neutrons
D) Sorry i don't know any uses of Carbon-12 and Carbon-13, you might have to research to get it.
E or F) Sodium 23 has 12 neutrons and 11 electrons, because its mass number 23, atomic number is 11 and since protons and electrons count is same, the number of neutrons = mass number - atomic number = 23 - 11 = 12 neutrons

<h2>Answer:</h2>
The compound is known as the neurotransmitter or messenger chemicals.
<h3>Explanation:</h3>
- Neurotransmitters are the chemicals a type of messenger which is used to transmit information from one cell to the next cell.
- Some hormones are also known as messenger chemicals.
- The nerve cells are not linked to each other while they are separated from each other by a space known as synapses.
- The electric potential signal is converted into chemical signal by the release of neurotransmitters.
- These neurotransmitter signal next cell to produce equal amount of electric signal in nerve cell.
A cell phone takes up more space than a feather, which is why it has more mass.
