Describe how an iconic bond happens.
How an iconic bond happens is that two elements exchange electrons which leads to full outer valence shells,an electric attraction, and an iconic bond.
Both calcium chloride and magnesium chloride have high melting points. What does this mean for their conductivity?
What this means for their conductivity is that their capability to conduct electricity is strong.
Water is a covalent compound. Why??
Water is a covalent compound because it shares electrons.
What elements make covalent bonds? What elements make iconic bonds?
Elements that make covalent bonds are hydrogen oxygen nitrogen and carbon. These elements make covalent bonds because they share electrons to each other. Elements that make iconic bonds are sodium and chlorine. These elements make iconic bonds because they transfer electrons to each other
How many valence electrons does nitrogen have?
5 valence electrons
How much is a mile? Why do we use the mole?
A mole is 6.02 × 10^23. We use the mole in order to count atoms.
