Answer: E = - 19.611×
J
Explanation: The lowest possible energy can be calculated using the formula:
where:
Z is atomic number of the atom;
k is a constant which contains other constants and is 2.179× J
n is a layer;
For the lowest possible, n=1.
Atom of Lithium has atomic number of Z=3
Substituing:
J
<u>The energy for the electron in the </u>
<u> ion is - 19.611 joules</u>
Answer:
Sufficient concentration and correct orientation of particles
Explanation:
The collision theory postulates that, for a chemical reaction to occur, there must be collision between reacting particles.
It implies that the rate of reaction depends on the number of collisions per unit time as well as the fraction that are successful or effective.
For collisions to be effective, there must be proper orientation of the particles and right concentration of the reactants.
- The number of effective collisions and rate of reaction are directly proportional to the concentration of of the reactants.
I believe the correct answer from the choices listed above is the third option. Scientists who possess honesty always report their observations and results truthfully. It <span> connotes positive and virtuous attributes such as integrity, truthfulness, straightforwardness. Hope this answers the question.</span>
