Answer:
D. They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
Answer:
has 6 valence electrons as its in group 6
the atom will gain electrons
the charge will be 2- as it will gain 2 electrons to be a full configuration
The balanced reaction is:
<span>4 Al + 3 O2
--> 2 Al2O3</span>
Each Aluminum atom wants to lose 3 electrons to become
isoelectronic with Oxygen. Each Oxygen on the other hand wants to gain 2
electrons. Since the reaction shows 6 Oxygen atoms in the product and each want
to gain 2 electrons, therefore a total of 12 electrons are transferred. Since
the problem ask for the electrons transferred per formula unit, hence:
<span>6 electrons (ANSWER)</span>
