When an atom loses or gains a proton the atomic number is changed making it change what element it is.
Answer:
- <u><em>Option D. There will be a shift toward the reactants.</em></u>
Explanation:
The reaction is:
The application of LeChatelier's principle leads to consider the <em>heat</em> as a <em>reactant</em> or a product depending on if it is on the left side or the right side.
In this reaction, the <em>heat</em> is on the left side, thus it must be considered a <em>reactant</em>.
Decreasing the temperature is equivalent to remove or consume heat. Thus, the reaction must shif to the left to compensate that reduction of heat. That is the reverse reaction shall be favored.
In conclusion, <em>there will be a shift toward the reactants.</em>
Answer:
The assumptions of the Bohr model of the atom are:
- Atoms have a central nucleus with electrons in orbit about this nucleus.
- They must gain energy to jump to a higher level, and they release energy when jumping to a lower level.
- Electrons orbit the nucleus, but the orbits can have only certain sizes and energy values.
Explanation:
The Bohr model of the atom establishes that atoms have a central nucleus with positive charge and electrons (with a negative charge) in orbit about this nucleus. In the Bohr model, electrons move in specific orbits with a certain amount of energy and can't jump from one orbit to another around the nucleus. To jump to a higher level, they must gain energy or release energy when jumping to a lower level.
The Thomson model of the atom postulated that <em>atoms are solid spheres of matter</em> and <em>are made of positive material with electrons fixed in place in this positive material</em>.
