Are scientists able to identify elements in stars by studying their spectral lines?
Yes, they are.
Why do scientists believe that stars contain the same elements as the solar system?
The elements on the visible part of distant stars can be obtained from the star spectra, that is, by analyzing the light that comes from the stars.
How do astronomers identify elements of the stars?
Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.
What instrument is used to tell what a star is made of?
Spectrometers are used for this. By looking at the spectrum of light coming from the star, scientists can tell which elements are in the star by the pattern of lines that are known to be associated with certain elements.
How did scientists confirm that the sun has hydrogen and helium power?
from energy spectrum of the of the sun it normally done in laboratory even for finding the elements present.
What kind of scientists studies elements atoms and molecules?
Chemists.
What element exists as molecules containing eight atoms?
Elements normally do not form "molecules" apart from 3 gaseous elements which form diatomic molecules. However, Sulfur exists in molecules comprising 8 atoms, while Phosphorous exists as a 4 atom molecule.

What is a substance that is a compound?
1. Compound and substance are synonyms. 2. A compound is formed from molecules containing two or more elements.
Are elements and compounds made of atom?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).

Are molecules and elements the same thing?
Molecules and elements are not the same thing. There are many molecules in elements but not elements inside of molecules.
Is a element a molecules?
Molecules are not elements. Elements make up molecules, though.
Which of the following elements exists as diatomic molecules?
Fluorine, Chlorine, Bromine, Iodine, Oxygen, Nitrogen and Hydrogen all exist as diatomic molecules.
Which of the following elements have molecules as their basic units?
A.chlorine B. silver C. helium D. hydrogen The answer is A and D
How are elements and molecules related?
Elements chemically combine to make molecules.
