Answer:
The chemical element neon is classed as a noble gas and a nonmetal. It was discovered in 1898 by William Ramsay and Morris Travers.
Yes neon is a magnetic
-248.6 °C
Neon/Melting point
Answer:
4HNO3 + Cu —> Cu(NO3)2 + 2NO2 + 2H2O
Explanation:
Cu react with HNO3 according to following equation
4HNO3 + Cu —> Cu(NO3)2 + 2NO2 + 2H2O
What an electron and a neutron have in common is that <u>each particle exists inside an atom,</u>
Atoms consist of three particles: protons (which are positively charged), electrons (which are negatively charged), and neutrons (which have no charge).
In keeping with the general trends, K-Br will have the smallest bond energy. The bond energy refers to the energy that keeps the atoms in a bond together.
<h3>What is bond energy?</h3>
Bond energy is the energy that is required to hold atoms together in a bond. This energy must also be supplied when the atoms are to be separated.
We have the bond energies of each of the bons in the question, we have to note that the the smallest value of bond energy is Na-Br hence in keeping with the general trends, K-Br will have the smallest bond energy.
