The Lewis structure of P₄ is shown in 3-D form. The two bottom corner P atoms are facing right in front of us, one P atom behind the two, and one P above it. Each line represents 2 electrons. When you add the lone electrons, you get a total of 20 valence electrons.
Formal charge of each P: 5 - (2 +1/2*6) = 0
<u>The frequency of </u><u>collisions </u><u>between the two reactants increases as the </u><u>concentration </u><u>of the reactants increases</u>. When collisions happen, they don't always cause a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations result in more collisions and reaction opportunities.
Increasing a reactant's surface area increases the frequency of collisions and thus the reaction rate. The surface area of several smaller particles is greater than that of a single large particle. The greater the available surface area for particles to collide, the faster the reaction will occur.
<h3>How does concentration affect the rate of collisions between reactants?</h3>
Thus, we can conclude that by increasing the concentration of Mg in the reaction mixture we increase the rate of collisions between the reactants in this reaction.
<h3>What does the half reaction of an oxidation-reduction reaction show?</h3>
Iron gains electrons in the half reaction of an oxidation-reduction reaction. What does iron's electron gain mean? It has been reduced. Predict the product that will precipitate out of the reaction using the solubility rules and the periodic table.

Answer: Rb (rubidium) has a radius of 290 pm, making it have the largest of the 5 elements listed.
Explanation:
When a molecule is broken down into its constituent atoms, these atoms do not have the same properties as the molecule.
We can use an everyday molecule, such as water, H20, to show this property. Water is a liquid with unique properties that stem from its hydrogen bonding. On the other hand, its constituent atoms, hydrogen and oxygen, are not liquids, and have very different properties. Oxygen and hydrogen are both gases; hydrogen is dangerous and very flammable, while we breathe in oxygen throughout our lives. This example illustrates how the atoms that make up a molecule usually have different properties than the completed molecule.
Hope this helps!
