Answer:
Diamond
Explanation:
Diamond has covalent bonds, which makes it a non-metal.
However, it also has a tetrahedral structure, which holds its C atoms together by strong forces, thus making it hard.
Diamond also has free-moving electrons due to its tetrahedral structure, thus making it possible to conduct electricity.
D.
The products will have at least 2 Na atoms and 1 O atom.
<h3>Further explanation</h3>
If we refer to the law of mass conservation, which states that
<em>In a closed system, the masses before and after the reaction are the same
</em>
then the number of atoms in the reactance will be the same as the number of atoms in the product
In this problem it is known that Na₂O is one of the reactants so that the product of Na atoms and O atoms will at least equal the number of atoms in the bond, namely 2 Na and 1 O
Like an example of this Na₂O reaction:
Na₂O + H₂O ⇒ 2 NaOH
Na : left =2, right = 2
O : left=2, right = 2
Answer:
A and 3
B and 2
C and 1
Explanation:
<em>Ion</em>ic bonding is the transfer of electrons from a cat<em>ion</em> to an an<em>ion</em>.
Covalent bonding is the sharing of electrons between nonmetal atoms.
<em>Metallic</em> bonding is the sea of electrons <em>metal </em>cations.
