What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
Which two of Dalton's theory were incorrect?
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
Which is a property of all atoms?
Which of these is always true of atoms? protons, electrons AND neutrons are always equal in number they are always bonded to another atom they always have a charge they are always neutral in elements
Is it true Different isotopes for the same element will always have the same numbers of neutrons?
Yes. it is true. Isotopes of the same element always have different number of neutrons.
What part Dalton atomic theory was later proved to be incorrect?
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
What is always the same for any given element?
The number of protons.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
Do the nuclei of all atoms of a given element always have the same number of neutrons?
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.
The nuclei of all atoms of a given element always have the same number of what?
Protons and Electrons
Which two of Dalton's theory were incorrect?
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
Why is the suns spectrum and the moon's spectrum the same?
Because the light we see given off by the moon - is actually the reflection of sunlight. Therefore they will have the same spectrum. The moon does not generate its own light.
Atoms of the same element always have the same number of what?
All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.
Which is a property of all atoms?
Which of these is always true of atoms? protons, electrons AND neutrons are always equal in number they are always bonded to another atom they always have a charge they are always neutral in elements
A given compound is always made of the same elements in the same?
A given compound is always made of the same elements in the same proportion.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
