What else can I help you with?
What instrument can be used to determine the identity of an element if its flame color is the same of another element?
Mass spectrometer would work.
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
Suppose you were given an unknown liquid and asked to determine if it was an element a compound or a mixture What would you do How would this help you find out what it was?
If I was given an unknown liquid and asked to determine if it was an element, a compound, or a mixture I would heat the unknown liquid up to see if any compounds separated from the unknown liquid. After that I would get a microscope and look to see if it is a pure element. Then I would get a Platelet separation machine and put the liquid in the machine to see if the liquid separated. Thats how I would determine if the an unknown liquid is an element, a compound, or a mixture.
What are three compounds of gold?
There are an extremely large number of possible gold compounds (billions would be a tremendous underestimate). An exact number is utterly impossible to determine.
Why would it probably be difficult to determine the chemical and physical properties of a newly discovered synthetic element?
Any newly discovered synthetic elements are extremely radioactive and have extremely short half-lives and only a few atoms at most can be produced. At the moment, science is not able to isolate enough for a long enough time. Therefore, it would be difficult to collect and keep enough of the element to determine its chemical and physical properties.
What instrument can be used to determine the identity of an element if its flame color is the same of another element?
Mass spectrometer would work.
How can one determine the density of an element?
To determine the density of an element, you would need to measure its mass and volume. The density of an element is calculated by dividing its mass by its volume. The formula for density is: Density Mass / Volume. By measuring the mass and volume of the element, you can then calculate its density.
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.

What does oxidation number for an element tell you?
The oxidation number of an element tells you the charge that the element would have if electrons were transferred completely during the formation of a compound. It can help to determine the type of chemical reactions that an element is likely to undergo.
How can one determine the oxidation number of an element?
To determine the oxidation number of an element, you need to follow specific rules based on the element's location on the periodic table and its chemical bonds in a compound. The oxidation number is the charge an atom would have if the compound was ionic. It can be found by considering the number of electrons gained or lost by the element in a compound.
Can you determine whether the atoms are the same element with out looking at the nuclei?
To a certain extent yes. In a balanced element the number of electrons match the number of protons in the core of the element. If electrons have been added or removed (as in an ion) then you would need to know the exact number added/removed, or rebalance the element, in order to determine the specific element.
What are the protons and newtrons of a banana?
A banana is not an element. You would have to determine the specific elements present and then figure out what their proton and neutron counts are.

What are valence electrons and what do they determine?
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
What has the mass number of 41?
The mass number of an element is the total number of protons and neutrons in its nucleus. Given that the atomic number (number of protons) uniquely identifies an element, knowing just the mass number of 41 is insufficient to determine the specific element without additional information.
