Answer:
carbon-12
Explanation:
carbon 6/12 isotope has 6 neutrones and it is considered as a metal.
Answer:
temperature and mechanism
Explanation:
Arrhenius equation gives us the idea about the factors affecting equilibrium constant.It is given as:
<h3>

</h3>
where k=equilibrium constant
A=pre-exponential factor
=Activation energy
T=temperature
R=Universal gas constant
<h3>It is clear that k depends only on temperature and activation energy.</h3>
Activation energy of a reaction is different for different mechanisms or pathways.Hence k depends on both temperature and mechanism.
<span>Electronegativity means the ability to attract electrons. Since He is a noble gas, it does not attract any more electrons. Cesium and Calcium are both metals, which lose electrons.
Fluorine is the right answer. It is highly electronegative which is the reason that fluorine is considered the most reactive non-metal.</span>
