No two distinct elements have the same atomic number. The atomic number is the number of protons an element has and is what makes it that particular unique element.
Isotopes do have the same atomic number however they belong to the same element because an isotope is just a form of the element with more or less neutrons in the nucleus, not a different element.
An example would be Hydrogen, it has three Isotopes:
Hydrogen-1 its nucleus is composes of just a single proton.
Hydrogen-2 or deuterium has a proton and a neutron in its nucleus.
Hydrogen-3 or tritium has a proton and two neutrons in its nucleus.
Notice that they all have just one proton, this by definition makes them all hydrogen atoms, and considered to be the same element.
What else can I help you with?
How many neutrons are found in an atomic nucleus?
It would depend on which isotope of which element. Different elements and isotopes of those elements do not have the same number of neutrons. Some have none, some have many.
When the elements on the periodic table are arranged by increasung atomic number the atomic mass generally increases as the atomic number increases. for some elements however the atomic mass of the el?
It is difficult to be sure what the question is about because it has been truncated.However, it is true that the atomic mass (or standard atomic weights) increases with atomin number. There are, of course, isotopes of elements with a low atomic number which are heavier than atoms of higher atomic number. But there are some examples where the average mass is not in the expected sequence.
Do some elements next to each other the same number of neutrons how is that possible?
Yes, some elements can have the same number of neutrons despite being different elements; these are called isotopes. Isotopes are variants of a chemical element that have the same number of protons (and therefore the same atomic number) but different numbers of neutrons. For example, carbon-12 and carbon-14 are both isotopes of carbon, with 6 neutrons and 8 neutrons, respectively. This phenomenon occurs because the atomic mass of an element is determined by the total number of protons and neutrons, allowing for variations in neutron count while maintaining the same atomic identity.
Do all elements in the same group have the same atomic mass?
No. Atoms of the same element can have different masses as the number of neutrons can vary. Atoms of the same element but with different masses are called isotopes.
Do some atoms have more or fewer protons than will other atoms of the same element?
No. The atomic number of an element is determined by its number of protons. If two atoms have different numbers of protons, they have different atomic numbers and are different elements.
Why do some properties of elements repeated in periodic patterns?
The periodic patterns in the properties of elements are due to their similar electron configurations and atomic structures. The periodic table organizes elements based on increasing atomic number, which leads to recurring patterns in their physical and chemical properties. These patterns occur because elements within the same group have the same number of valence electrons, which governs their behavior.
Can some elements have the same number of electrons in their outermost level?
Elements in the same group have the same number of valence electrons.
Why some elements possess fractional atomic mass?
It is mostly because elements have many isotopes and their average comes to be also fractional.We cannot weigh the atom therefore its atomic mass is fractional.Even elements with only 1 naturally occurring isotope have fractional mass. This is because the nuclear binding energy is a very large (negative) energy, and it shows up in the atomic mass because of the relativistic adjustment that has to be made --E= mc2,
Is it true that the elements on the periodic table are arranged by the number of NEUTRONS?
No, they are organized by numerous factors (such as free electrons and number of orbital shells) but are given their periodic number based on their electrons.No. They are arranged by the number of protons which is the same as the number of electrons.
Are elements different from other elements?
Yes, elements all have a different amount of protons in their atoms (number of protons = atomic number), but some elements have similar properties. For instance, the alkali metals all react in water, getting more violent as the atomic number gets higher.
What four things does a periodic table tell us?
The periodic table tells us:The elements atomic massThe elements atomic numberIf the element is a gas, metal, etc.How many protons, electrons and neutrons an element hasThe name of the elementWhich elements could have similar properties (nearby in the chart)(Oops that was already six things (but some of them depend on the others)
True or false- all atoms of the same element have the same atomic number?
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
