The lattice energy is the amount of energy released when the ions that make up a crystal lattice are brought together. Now, this energy is dependent on the charge concentration of these ions. Both potassium and rubidium form ions with a +1 charge, while bromine and iodine form ions with -1 charge. However, because potassium and bromine are smaller than rubidium and iodine respectively, the charge is more concentrated. Therefore, more energy is released when potassium and bromine are brought together.
Answer:
d. decomposition
Explanation:
decomposition reaction is a reaction in which a compound breaks down into 2 or more substances.
the general form is: AB → A + B
Answer:
eight strong bonds to the atoms that it touches and six weaker bonds to the atoms it almost touches. This makes it easier to understand why a metal might prefer the body-centered cubic structure to the hexagonal or cubic closest-packed structure.
Alpha particles, also called alpha ray or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a <u>helium-4 nucleus. </u>They are generally produced in the process of alpha decay, but may also be produced in other ways.
Composition: 2 protons, 2 neutrons
Mass: 6.644657230(82)×10−27 kg; 4.0015061...
Electric charge: +2 e
Symbol: α, α2+, He2+
Answer:
The answer is B
Explanation:
The area surrounding the nucleus is called the electron cloud which holds the electrons, so with the power of deduction its B. 0-0
