There are few elements that can form 12 electron rather than the usual 8. Therefore these are the possible answers:

Sulfur = 2Na + S --> Na2S <span>
Selenium = 2Na + Se --> Na2Se 
<span>Tellurium = 2Na + Te --> Na2Te</span></span>

A compound that allows for communication between one cell and the next is called _________
-Dominant- [34]
<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.

Explain percent ionic character of a bond. Explain percent ionic character of a bond. Percent ionic character is defined as the
disa [49]

Answer:

Percent ionic character is defined as the ratio of a bond’s actual dipole moment to the dipole moment it would have if the electron were completely transferred from one atom to the other, multiplied by 100

Explanation:

The percent ionic character seeks to establish the amount of electrovalency in a particular compound. It simply compares the covalency i.e extent of shared electrons to the the electrons that are transferred.

It is given as the ratio of the acutal dipole moment to the dipole moment due to ionic character of the bond multiplied by 100:

Percent ionic character = μ_obs/μ_ionic x 100

Where μobs is the actual dipole moment and μ ionic is the dipole moment if the bonds were 100% ionic.
