How do atoms differ one another?

Answer 1

Atoms of different elements are different because the have different numbers of protons. The atomic number (the number of protons) is what defines which element the atom is. For example, all atoms containing 1 proton are hydrogen. 2 protons are helium, 3 lithium and so on. See the Periodic Table of elements for more. Atoms of the same element can still be slightly different in the number of neutrons they have; these are called isotopes. Their properties stay the same but they have different masses. You need not consider electrons too much because most atoms have a relatively loose hold on electrons and don't account for much mass BUT!!!! electron configuration is the main factor for determining how elements will react with each other.

Answer 2

Atoms of the same elements have the same number of electrons, protons, and neutrons. Atoms of different elements have different numbers of electrons, protons, and neutrons. All protons are identical to one another.

Answer 3

More information would help.

It's like asking "How do chairs differ from other chairs?"

Seriously.

It helps to ask questions that make a lil' sense.

Presumably, the information you want is that some atoms have more or less neutrons, protons and electrons, changing their properties. For more information, check any science website, ever.

Answer 4

Elements are distinguished mainly by the number of protons they contain. For instance, oxygen has 8 protons, while zinc has 30 and iodine possesses 53. Other factors can enable us to differentiate between elements: appearance at room temperature, ability to conduct heat and electricity, etc...

Answer 5

We know that no. Of protons and electrons in a neutral atom of any element is same.since protons can't be in fractions therefore the no of protons will be in whole numbers.thus it will be like a series like 1,2,3,4.........thus different elements have different protons,thus atomic no is different .atoms with same atomic no are isotopes not atom of succeeding atom.thus atom of different elements is different..........

Answer 6

Atoms of different elements differ in pretty much every way : number of protons , neutrons , and electrons . The difference in proton number is what determines each unique element . (each element has a certain number of protons ; carbon has 6 protons , or else it's not carbon anymore) Different atoms of the same element , however , differ only in the number of neutrons . Atoms of the same element with different numbers of neutrons are called different isotopes . They are still the same element , and they behave the same way in chemical reactions , but they have different atomic masses and elements typically have one or more isotopes that are radioactive .

Answer 7

different numbers of protons and neutrons in their nucleus and electrons

Answer 8

Atoms differ in atomic number. The atomic number = the # of protons in the atom.

Answer 9

The essential difference is the number of protons.

Answer 10

There is a main difference. It is the number of protons.
