I think that, considering that a mole contains an Avogadro's number of elements, there should be 6.2× an Avogadro's Number of atoms of Al. 6.2×6.022×1023=3.733×10<span>24 atoms</span>
Answer:
Attached Lewis structure
Explanation:
To draw the Lewis structure, we need to consider the octet rule: atoms will gain lose or share electrons to complete their valence shell with 8 electrons. Hydrogen is an exception because it is completed with 2 electrons (duet). N and H are nonmetals so they form covalent bonds, that is, they share electrons.
- N has 5 valence electrons, so it has to share 3 pairs of electrons.
- Each H has 1 valence electron, so it has to share 1 pair of electrons.
The Lewis structure is attached and there are no resonance structures since there are no pi electrons.
Answer:
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
