For A+ the answer is False. Your Welcome fellow cheaters xD.
The spectral lines produced by elements are unique and distinct because they correspond to specific energy transitions within the atom, which are characteristic of each element. These lines are produced when electrons move between energy levels in the atom, emitting or absorbing light of specific wavelengths. This results in a pattern of lines that serve as a "fingerprint" for each element, allowing scientists to identify the elements present in a sample.
You could use spectroscopy to analyze the light emitted by the sun to look for the characteristic spectral lines of platinum. If you detect these specific spectral lines in the sun's spectrum, it would support the theory. Conversely, if you do not find these lines in the sun's spectrum, it would provide evidence against the theory.
Nobelium is a synthetic element that has only been produced in trace amounts and is not readily available for visual observation. Its appearance would be expected to be metallic and silvery-white in color, similar to other actinide elements.
Meitnerium is a synthetic element that is not found in nature. Since it is highly radioactive and unstable, it is only produced in laboratories and exists for a very short time before decaying into other elements. Therefore, it does not have a specific physical appearance.
Atoms heavier than iron are typically produced through processes like nuclear fusion in supernovae or in laboratories. Some examples include atoms like uranium, plutonium, and lead, which have more protons and neutrons in their nuclei compared to iron.

Look at lab 8.7, in your book. I lost my book so i cannot answer this for you... and its not in my notebook...good luck!i HATE ips...;)- carrott
They are the same.
If you want to know the elemental composition of a star, you look for the elements' fingerprints. These are in the form of line spectra, since each element has its own particular set of spectral lines. Atoms in the star's atmosphere will absorb their characteristic frequencies from the cavity radiation emitted from the star due to its temperature. Color

straight lines make you look skinny. horozontal lines make you look fat and diagonal lines make you look lopsided!!
Sirius A has a spectral type of A1V. So it has a colour of white to white blue.
These lines are perpendicular: _|
No. Look at the sky.
they help drawings look better,it is a great way to group together different elements in a photo and it helps to establish details within photographs such as:direction and location.
The Noble Gases are colourless, monatomic elements. When they are excited electrically, each gas exhibits a distinctive set of spectral lines, characteristic of that element. Helium has five lines in the visible spectrum dominated by yellow; Neon has quite a few lines in the visible spectrum but appears orange to red; Argon also appears orange to red and Krypton appears more green and Xenon is blue - green.
They look like two intersecting lines that make four right angles. Like the two lines in this L.
