Answer:
<h3>The answer is 0.23 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.23 moles</h3>
Hope this helps you
Answer:
B
Explanation:
The electronegativity of an atom is a chemical property of that atom that describes the tendency of the atom in question to attract a lone pair of electrons towards itself.
Across the periods, that is going from left to right on the periodic table, it is expected that there is an increase in the electronegativity of elements. Hence, there are more electronegative elements on the right hand side of the periodic table. Thus, we say chlorine or fluorine is more electronegative than either sodium and magnesium.
While it is expected to increase across the period, electronegativity decreases down the group. Hence, we know that chlorine is more electronegative than bromine while fluorine is more electronegative than chlorine. In fact, fluorine is the most electronegative element as it is the first member of the most electronegative group of elements.
Fluorine and oxygen are expected to undergo a covalent bond formation. Both are electron deficient and thus completes their electron orbits by entering into covalent bonding with each other
Answer:
B
Explanation:
As you move down the periodic table in the carbon family, the atomic radius and ionic radius increase while electronegativity and ionization energy decrease. Atom size increases moving down the group because an additional electron shell is added.
A very electronegative atoms has a strong ability of attracting electrons towards itself. As a result, it would gain electrons more than it usually has. Therefore, it would form an anion, or a negatively charge ion. These ions readily accepts electrons from the valence of other elements.
