Aside from determining how many electrons the atom has, the nucleus does not affect the spectra of that atom in any way.

Why was Moseley able to resolve the discrepancies in Mendeleev's table when Mendeleev could not?
Because by using the lines in the xray spectra of 38 different elements, he found that the lines were correlated to atomic number, not by atomic mass.
Which elements atomic nucleus contains 11 protons?
Sodium
What did Henry Moseley discover in science?
he knew that it had protons and neutrons and electrons but he thaught the charges where the wrong way round
What is the intra-atomic forces?
These are the nuclear forces (the strong interaction in the elements nucleus).
Why the em value of anode ray depend on the gas?
Actually it is due to the nucleus's. the protons + neutrons) of the individual atoms. Each element (or isotope) have different atomic mass (mainly due to the nuclear mass) and different atomic number (equal to nos of protons in the nucleus). The canal rays (also known as the anode rays are actually the nucleus of the atoms that have been ripped of electrons, hence acquiring an overall positive charge equal to the number of protons in the nucleus of the atom. But since different elements have different mass numbers and atomic numbers hence the e/m ratio varies for the elements canal rays.
What is the name of the spectrum when elements produce different colors when heated?
Atomic spectra
Does mendelevium have nucleus?
All the chemical elements have an atomic nucleus.
How do you identify a compound or an element?
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.
How do you find the number of protons in an elements nucleus?
The number of protons in an elements nucleus is the same number at the atomic number.
What does an elements atomic number tell about that elements?
Atomic number indicates the amount of protons present in the nucleus of an atom.
Why was Moseley able to resolve the discrepancies in Mendeleev's table when Mendeleev could not?
Because by using the lines in the xray spectra of 38 different elements, he found that the lines were correlated to atomic number, not by atomic mass.
Why using only Hydrogen atom in atomic spectra?
There are spectrums for many other elements too.
Which elements atomic nucleus contains 11 protons?
Sodium
What do elements have the same number of?
Elements have the same number of protons in each atomic nucleus.
What is the relationship between the atomic number and the elements identity?
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
How did Moseley discover the atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
What is the number of protons in an elements nucleus?
The same as its atomic number.
