∙ 10y agoAll atoms of one element have the same number of protons in their nucleus. The number of neutrons can vary (producing different isotopes of that element) and the number of electrons can vary (producing ions of that element) but the number of protons does not vary for one element, because if you alter the number of protons in a nucleus, you will then have a different element.

Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What is the difference between elements and atoms and compounds?
An atom is a structure of protons, neutrons and electrons. A collection of atoms that all share the same number of protons are all given the same element name (i.e. all carbon atoms have exactly 6 protons, and all helium atoms have 2). a compound is a collection of atoms of different elements that are bonded together. A good example of this is water, which is made of two Hydrogen atoms and one Oxygen atom bound together.
What happens to the number of atoms in 1mol of each elements in the periodic table increase?
One mole of any element will have Avogadro number (6.023 x 1023) of atoms And this number remains the same for all elements.
Do all atoms have the same protons?
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
What is an atom that has the same number of neutrons as all other atoms of the same element?
An atom of one of the few elements that have only one radioactively stable isotope naturally occurring. Even this is not quite literally true, because all atoms have radioactively unstable isotopes that have different numbers of neutrons.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What is Dalton's four principles?
All elements are composed of atoms.All atoms of the same elementhave the same mass, and atomsof different elements have different masses.Compounds contain atoms of more than one element.In a particular compound, atoms of different elements aalways combine in the same way.

All compounds are formed of what?
all compounds are formed of one or more elements..
The elements in each____ have the same number of?
all the nuclei of all atoms belonging to one element will have the same atomic number, they may not necessarily have the same mass number
Would the atoms of one element be all the same or be different?
They are all the same in that they have the same numbers of protons and electrons and therefore react in the same way. However, most elements can have atoms with different numbers of neutrons (isotopes), and therefore different masses.
What happens to the number of atoms in 1mol of each elements in the periodic table increase?
One mole of any element will have Avogadro number (6.023 x 1023) of atoms And this number remains the same for all elements.
What are the four points of DaltonS theory?
The four points of Dalton's theory were: 1. All elements are composed of atoms. 2. All atoms of the same element have the same mass, and atom of different elements have different masses. 3. Compounds contain atoms of more than one element. 4. In a particular compound, atoms of different elements always combine in the same way.
Are some types of matter made up of atoms?
All matter is made up of atoms.Elements are matter which is made up entirely of one type of atom* Gold atoms are all the same * Iron atoms are all the same * Hydrogen atoms are all the same ...Compounds are matter which is made up of several elements * Salt contains Sodium atoms and Chlorine atoms, always in the same proportion of 1:1* Water contains Hydrogen atoms and Oxygen atoms, always in the same proportion of 2:1...Some compounds contain varying amounts of different elements * Brass is made up of Copper atoms and Zinc atoms. but the proportions vary with each sample * Steel is made up of Iron atoms and Carbon atoms and atoms of a number of other elements, again varying in proportion according to the sample being examined.
Do all atoms have the same protons?
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
A substance in which one or more atoms have the same number of atomic number?
No two elements have the same number of protons.
Are all atoms of a given element identical to one another and different from atoms of other elements?
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
