What else can I help you with?
Is an element's atoms are all the same or different?
same
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.
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
Do all atoms of the same element contain the same number of netrons?
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
How is are element and an atom different?
An atom is an individual particle made of protons(positively charged particles), electrons(negatively charged particles) and neutrons(particles with no charge). The type of atom depends on the number of protons in the nucleus(the centre of the atom). An element is all atoms of the same type.
What is a pure substance that has all particles the same?
An element.
Which is not part of John Dalton’s atomic theory a. Atoms of different elements have different masses.b. All elements are composed of atoms.c. All atoms of the same element have the same mass.d.Atoms are made up of smaller particles?

Is an element's atoms are all the same or different?
same
Do all the atoms have the same proton number?
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 element is composed of atoms that all have the same atomic number?
An element is composed of atoms that all have the same atomic number. Each atom of this element has the same number of protons in its nucleus, which determines the element's identity on the periodic table.
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.
Is it true that all particles are alike in elements?
No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.
Do the nuclei of all atoms of a given element always have the same number of neutrons?
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.
Did Dalton say that all atoms are the same size?
No, Dalton did not say that all atoms are the same size. Instead, Dalton proposed that all elements are composed of indivisible particles called atoms, and that atoms of different elements have different sizes and properties.
All particles in a pure material are the same true or false?
- A molecule may contain different types of atoms.- An element can be composed from different isotopes.
How are liquid particles gas particles and ice particles the same?
They are all made of matter; just in different states.
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element.
