<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.

What are 3 general rules to predict the stability of an isotope
Mashcka [7]
<span><span>1) Calculate the total number of nucleons (protons and neutrons) in the nuclide
<span>--> If the number of nucleons is even, there is a good chance it is stable.
</span></span><span><span>
2) Are there a magic number of protons or neutrons?
</span>--> 2,8,20,28,50,82,114 (protons), 126 (neutrons), 184 (neutrons) are particularly stable in nuclei.
</span><span>
3) Calculate the N/Z ratio.
<span>--> Use the belt of stability (Figure 1) to determine the best way to get from an unstable nucleus to a stable nucleus</span></span></span>

How do you determine valence electrons of a metal? A non Metal?
Harlamova29_29 [7]

Answer:

Check the electronic configuration of elements.

Explanation:

▪Valence electrons are the elwctrons present in the outermost shell of any element.

For example,

Electronic Configuration of Sodium = 2,8,1

Here , Sodium has 1 valence electrons.

▪Valency of an element is the total no. of electrons to be gained/losed in order to achieve duplet/octate state.

For example,

Electronic configuration of Sodium = 2,8,1

Sodium can achieve octate state either by losing 1 electron or gaining 7 electrons. But losing 1 electron is eay than gaining 7 electrons. So Valency of Sodium = +1

☆Metals have 1 or 2 or 3 valence electrons.

☆Non metals have 4 or 5 or 6 or 7 valence electrons.

☆Noble gases tend to stay in duplet/octate state i.e they have 2 or 8 valence electrons.
