What do you know about types of atoms before and after a reaction?

Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.

Is picking up iron filings with a magnet a chemical reaction?
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
What happens to the atoms within molecules undergoing a chemical reaction?
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
What is conserved in the reaction shown below. N g plus 3F g 2NF g?
Mass is conserved in any chemical reaction. If the reaction is balanced it will show that mass is conserved. In others words the mass of the reactants will equal the mass of the products...just to add the balanced reaction should be (i didn't know if you forgot the subscripts or not): N2 + 3F2 --> 2NF3 so is it atoms only mass only mass and atoms only or moles only
What happens when the same kind of atoms combine?
That is the process know as fusion. When the two atoms combine, a very small amount of matter is destroyed in the process. This results in a huge amount of energy release. Fusion is the thermonuclear reaction that powers the stars.
Why a chain reaction occurs when uranium-235 undergoes fission?
dont know it may be cuz of the cause of splitting atoms or it might be something else call need help at my email me up when you
Are there similar atoms on other planets?
Yes, as far as we know, the elements, composed of the same types of atoms, are the same everywhere.
What is the minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.
What are some different types of atoms?
i dont know thats ehy im asking you!
What is an elementary step and how is it related to the mechanism of the reaction?
You must know, 1- symbols of atoms, 2- electronic configurations of atoms,3- valency of atoms, 4- electrons donating or accepting abilities of atoms, 5- converion of masses into moles, 6- balancing of chemical equations and 7- conditions of reactng materials.
What refers to the new substances present after a chemical reaction?
result

What reaction types tend to react together the most rapidly?
If you mean what two element types then: Metals and non-metals If not, I do not know what you are asking
Why do we need to know the Gram reaction and morphology of an organism before performing biochemical testing?
No
Why was Dalton atomic weight table inaccurate?
-He didn't know the correct ratio of atoms in a chemical reaction and the equipment at the time did not have very accurate numbers.
Why do chemists use the mole as counting unit?
The mole is a convenient way to track and plan for efficiency in a chemical reaction. Imagine it this way, you know how old timers used "parts" in recipes? i. e. "one part sugar to two parts flour etc. . . ." It is the same thing with chemistry and moles. A mole is just a standardized "part", equal to the number of atoms in 12 grams (roughly) of Carbon. If you know the actual proportions of atoms/molecules in a reaction, you can know what the ideal yield will be as a reaction end result.
how do know what kind of sex your partner likes?
Try different types and see their reaction. Or you may just ask this to them to face.
