Which statement best explains how isotopes can have different masses and still be the same element? A. The quantity of protons identifies the element and cannot change; therefore, the neutron amount changes, ultimately changing the overall mass of the atom. B. The quantity of protons identifies the element but changes if the mass of the isotope differs from what is shown on the periodic table. C. The sum of the electrons and neutrons equals the isotope's mass with the proton amount being given by the atomic number. D. The sum of the protons and electrons equals the mass of the isotope, and the neutron amount is equal to the atomic number.

OpenStudy (agent0smith):

The neutron amount changes

OpenStudy (anonymous):

I'm still not sure

OpenStudy (ilovecake):

I think it is c or a but not sure.

OpenStudy (anonymous):

is it b?

OpenStudy (ilovecake):

For number 2

OpenStudy (anonymous):

ya

OpenStudy (ilovecake):

Yeah B

hello...

OpenStudy (anonymous):

It's B.

According to early chemists, which substances were classified as elements? A. those that had higher numbers of protons in their atoms B. those that had an atomic mass that could be measured C. those that could not be broken down further by physical means D. those that could not be broken down further by chemical means

OpenStudy (anonymous):

c?

OpenStudy (anonymous):

Yes it is C

It's right there in that answer

OpenStudy (ilovecake):

No not C. it is A like @agent0smith said.

OpenStudy (anonymous):

ya i reread it thx @agent0smith

On the periodic table, which group contains the noble gases?

OpenStudy (agent0smith):

According to early chemists, which substances were classified as elements? D. those that could not be broken down further by chemical means i think this would be the correct answer.

OpenStudy (anonymous):

On the periodic table, which group contains the noble gases?

OpenStudy (anonymous):

the last group A. the fourth group B. the second group C. the first group D.

OpenStudy (agent0smith):

Noble gases are at the end of the periodic table, last

OpenStudy (anonymous):

b?

OpenStudy (anonymous):

hello

OpenStudy (agent0smith):

molecules
