A bond of the following elements would be of what type? Ca + 2Cl<br><br> Covalent or ionic
dedylja [7]

Answer:

Ionic

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

calcium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for calcium is 1. There is large difference is present. That's why electron from calcium is transfer to the chlorine. calcium becomes positive and chlorine becomes negative ion.

There are two valance electrons in calcium so it needed to lose two valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus two electrons lost by one calcium atom are gained by two atoms of chlorine.

Ca + Cl₂ → CaCl₂

The amygdala is thought to control defensive behavior via outputs from the _____ nucleus of the _____.
Anika [276]

The amygdala is thought to control defensive behavior via outputs from the central nucleus of the amygdala

What does the Amygdala do?

It is crucial in processing and regulating emotional reactions. Especially important in strong emotional reactions such as fear and anger

What does the amygdala control?

The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli , including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.

Central nucleus of Amygdala :

The central nucleus of the amygdala (CeA) has been traditionally viewed in fear conditioning to serve as an output neural center that transfers conditioned information formed in the basolateral amygdala to brain structures that generate emotional responses.

What does the central nucleus consist?

The central nucleus of the amygdala (CeA) is primarily composed of GABAergic interneurons which are finely controlled through glutamatergic neurotransmission and signaling. The CeA can be divided into the medial (CeM) and lateral (CeL) divisions
