Yes. All atoms of an element contain the same number of protons. That is the defining characteristic of an element.
Isotopes are variants that have differing numbers of neutrons. However, when the proton number changes (through bombardment in a particle accelerator or through radioactive decay), the differing proton number makes it, by definition, a new element.
For example, carbon-12 and carbon-14 are isotopes containing different numbers of neutrons. However, both atoms are the same element, carbon, because each has the same number of protons (six).
However, when uranium-238 loses an alpha particle (a helium-4 nucleus, consisting of 2 protons and 2 neutrons), it decays into a different element (thorium-234), because it now has a different number of protons (90).
When an atom decays via beta decay, one of its neutrons decays into a proton, an electron, and an antineutrino. The important part here is the additional proton, which slightly decreases its mass and increases its proton count. Since the baryon count (neutrons + protons) did not change, its Atomic Mass number does not change.
Example:
Lead-210 (82 protons, 128 neutrons = mass of 210)
--> decays by beta emission (one of its neutrons decays into proton + electron + antineutrino...electron and antineutrino are released...proton stays in nucleus)
--> becomes bismuth-210 (83 protons, 127 neutrons = mass of 210)...different element...same atomic mass (in terms of baryon count alone, that is).
What else can I help you with?
Of what are atoms composed?
Atoms are composed of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus in energy levels.
How many protons and electrons are in argon?
There are 18 electrons and protons each in argon atoms.
Which came first atoms or electrons?
Of the two, electrons. (Protons had to form, perhaps from quarks, before the first atoms could form and the temperature had to be cool enough for protons and electrons to come together to form hydrogen.)
Atoms composed of what?
Atoms have three subatomic particles; viz., protons, neutrons and electrons. The protons, and neutrons are in the nucleus of the atom and are collectively named as 'nucleons'. Electrons are in energy shells outside and around the nucleus. Atoms with a different number of protns and different elements.
Does Neutral potassium atoms contain more protons than electrons?
No, any neutral atom contains the same number of protons as electrons. Protons have a positive charge, and electrons have a negative charge, so in order to be neutral, the numbers of protons and electrons have to be equal.
Are atoms are NOT composed of protons neutrons electrons xenon's?
All atoms have neutrons, protons and electrons.
When atoms are at rest what do they have an equal number of?
protons and electrons protons and electrons
What from atoms?
Atoms are composed of protons, neutrons and electrons.
What are made of elements?
atoms: protons, electrons, neutronsElements are made up of atoms or electrons or protons but i know it has to be one of thoes.
Of what are atoms composed?
Atoms are composed of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus in energy levels.
How many electrons and protons in argon?
There are 18 electrons and protons each in argon atoms.
How many protons and electrons are in argon?
There are 18 electrons and protons each in argon atoms.
What are protons and electrons compressed in?
in Atoms.
Do atoms lose protons but seldom lose or gain electrons?
Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.
How do you describe atoms?
Atoms have a Nucleus, Protons, Nuetrons, Electrons!
In atoms electrons and protons are in the same ratio or different ratio?
protons and electrons are identical in number in an atom
Is most atoms have more electrons than proton?
Yes, most atoms do have more electrons than protons. This is because atoms are electrically neutral, and the number of protons (positive charge) in the nucleus is balanced by the number of electrons (negative charge) surrounding the nucleus.
