Anitrogen atom contains seven protons, seven neutrons, and seven electrons. make a labeled drawing of the structure of a nitrogen atom. how can this atom become stable?

A nitrogen atom can achieve stability if an atom of another element gives nitrogen three electrons or shares three electrons with it. Below is an explanation and drawing about the nitrogen atom.

Explanation:

A nitrogen atom contains seven protons, seven neutrons and seven electrons. In the valence layer of the nitrogen atom are 5 electrons, this means that this atom needs to gain 3 electrons to reach its stability since there is a rule that each atom needs to have 8 electrons in its valence layer to achieve stability, except for the hydrogen atom that only needs 2 electrons. Because of this rule, it is necessary for the nitrogen atom to receive 3 electrons from another atom, or to share 3 electrons with another atom, an example of which are compounds N2 and NH3.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
