Why was daltons model accepted?
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
How did Moseley discover the atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
How do you disarm an atomic bomb?
Figure out a way to remove the nuclear material, and there will be no reaction. Unfortunately, atomic bombs are usually dropped from the sky, detonating on impact.
What identifies and element?
Atoms are differentiated by their number of protons. This is equal to the atomic number of the element. Additionally, in chemical formulas, each element is represented by a unique atomic symbol.
What type of reaction occurs in a atomic bomb?
An atomic bomb primarily relies on nuclear fission, a reaction in which the nuclei of heavy atoms, such as uranium-235 or plutonium-239, split into smaller nuclei when struck by neutrons. This process releases a vast amount of energy, as well as additional neutrons that can trigger further fission events, leading to a rapid, uncontrolled chain reaction. The immense energy released in a very short time results in the explosive force characteristic of an atomic bomb.
Is atomic nuclei required in a chemical reaction?
No, atomic nuclei is not required for a chemical reaction.
What goes under no chemical change in a chemical reaction?
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
Is platinum a chemical reaction or a physical reaction?
neither, platinum is an element. It has a atomic number of 78 and an atomic weight of 195.08. It's chemical symbol is Pt.
Do all chemical reactions need atomic nuclei?
All atoms involved in a chemical reaction have an atomic nucleus.
Which of the following is not required in a chemical reaction?
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
Which sub-atomic particle creates chemical reaction?
Proton and Neutron do not take part in chemical reaction. Only electron takes part in the reaction.
Why atomic number not change during a chemical reaction?
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
Daltons thrid postulate states that atoms can be destroyed by?
Dalton's third postulate states that atoms cannot be created or destroyed in a chemical reaction, they can only be rearranged. So, atoms cannot be destroyed by any chemical process as per Dalton's atomic theory.
How does Daltons atomic theory explain the law of definite proportions?

According to Dalton what happens to atoms during a chemical reaction?
Combine with other atoms Separate from other atoms they are already attached to.
Where is the energy which is released during a chemical reaction stored to begin with?
The energy released during a chemical reaction is stored in the chemical bonds of the reactant molecules before the reaction occurs. During the reaction, these bonds are broken, and new bonds are formed, releasing the stored energy in the process.
The weight in daltons of one atom of an element is?
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
