What are atoms with the same number of protons and different numbers of neutrons called?
Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the periodic table of elements. The existence of isotopes was first suggested in 1913 by a radiochemist named Frederick Soddy.
What are the similarities and differences among the isotopes of an element?
Similar in number of protons, electrons, thus in chemical properties, except in nuclear reactions. Different in number of neutrons, mass and a lot of physical properties.
What is an atoms spectrum?
when a beam of white light is passed through the vapours or a gas, the element absorbs certain wavelengths, while the rest of wavelengths are passed through it. The spectrum of this radiation is called atomic absorption spectrum.The missing wavelengths appear as dark lines in the spectrum.
How are istopes formed?
Isotopes are formed through variations in the number of neutrons in the nucleus of an atom
What is the atomic emission spectra?
The colors of light given off when an element loses energy
What does it means if an isotope is fissile?
Fissile isotopes are isotopes of an element that can be split through fission

How many isotopes does copper have?
Copper has natural isotopes of 63,67. And other isotopes are known at least from 58 through 70. But these are unstable.
How was the existence of helium confirmed in the sun?
Through the spectrum. Signatures of an element was found that was not known on Earth. Some years later, it was also found on Earth. Hence the name, "helium".Through the spectrum.

What are some examples of uranium?
The only distinct examples of an element are its isotopes, unless one wishes to consider the compounds of the element as examples. By 1985, isotopes of uranium with every integral mass number from 226 through 240 had been reported, along with U-242.
Why can elements in a star be separated?
Because the spectrum of the star's light can be seen to have dark lines all the way through, and each element has its own set of dark lines in the star's spectrum.
How are isotopes are formed?
Isotopes are formed either naturally through radioactive decay of elements or artificially through element irradiation by particles as neutrons, protons, electrons, or alpha particles in accelerators or nuclear reactors through nuclear fission or nuclear fusion reactions in nuclear reactors.supernovasparticle acceleratorsnuclear reactorsnuclear explosionsradioactive decay
How much effect do high percent abundance isotopes have on the average atomic mass of an element?
This entirely depends on the percentage of the different isotopes present. This is typically determined through mass spectrometry. After the percentages of the different isotopes are known, one times the percentage of each isotope by its relative atomic mass, then add this all together. After dividing this by 100, you will have attained the average atomic mass of a naturally ocurring element.
What are the isotopes of Na?
18Na through 37Na are all the isotopes of Na.

What is a prism and what does it do to a white light?
They separate light into the light spectrum. If a beam of light shines through a prism, a rainbow of color will show out through the opposite side.
