What else can I help you with?
What element has 121.75 as it's atomic weight?
The element of Antimony (Sb) would have the atomic weight of 121.75.
What element has the atomic number of 202?
There isn't an element with the atomic number 202 because the known elements in the periodic table have atomic numbers up to 118, which is Oganesson. Any element with an atomic number higher than 118 would be highly unstable and would not exist naturally.
What element has the atomic mass of 32.065?
Sulfur is a non meta element. Atomic mass of it is 32.065.
How do you convert between the molar percentage of a compound e.g. CaO and the atomic percentage of the elements e.g. Ca and O?
To convert from the molar percentage of a compound to the atomic percentage of its elements, you can use the molar mass of each element to calculate the number of moles of each element in one mole of the compound. Then, you can use these values to determine the atomic percentage of each element. For example, in CaO, one mole of CaO contains 1 mole of Ca and 1 mole of O. So, the atomic percentage of Ca would be (molar percentage of CaO) * (molar mass of Ca) / (molar mass of CaO), and similarly for O.
How is the number of electrons is a neutral atom of a given element related to the atomic number of that element?
The atomic number tells you how many protons are in the element. The proton count is the same as the electron count as all elements have a charge of zero giving them the same. Simplified: the atomic number shows you how many electrons and protons are in the element. If it is a compound and it has a charge of +1 that means the element has lost one electron and has a positive charge. If it gained a electron it would be -1 as electrons are negatively charged.
Is chlorine a element or compound or a mixture?
Chlorine is an element on the periodic table. If you look, its average atomic mass is 35.5 amus. It would be a compound if it was 'connected' with another element, ie Hydrogen. HCl is considered a compound, but chlorine (Cl) alone is just an element.
Would gold be a compound or element?
Gold is an element with the symbol Au (Due to its Latin name Aurum).
Is Ca a suspension solution mixture compound or element?
Ca is the chemical symbol for calcium, an element. It is an alkali metal with atomic number 20. ------------------------------------------- The above is true, however if the element Ca is present in a solution then it will be present as part of an Ionic compound in solution, note a solution is not a mixture, element or compound, it is a SOLUTION. An insoluble compound of Ca could be present in liquid, in which case you would have a suspension. A suspension is a mixture.
Suppose a new element is added under francium in the periodic table what would its atomic number be?
If a new element is added under francium in the periodic table, its atomic number would be 119. Francium has an atomic number of 87, so the next element in the periodic table would be the one with an atomic number of 88, which is radium. The subsequent element would have an atomic number of 119.
What element is in a black hole?
It is not expected that elements would survive as such, within a black hole. Gravitational force would crush everything together to the point where no atomic nuclei remain intact.
Where would a new element with an atomic number of 113 be placed?
The element with an atomic number of 113 is Ununtrium.
What element has an atomic number that is doubled the atomic number of silicone?
Silicon is a non meta element. Atomic number of it is 14.
Is magnessium a compound or element?
From Wikipedia (which, should you use - say - Google, would have provided a quick and cheap answer):Magnesium (pronounced /mægˈniːziəm/) is a chemical element with the symbol Mg, atomic number 12, atomic weight 24.3050 and common oxidation number +2.-matt

How many electrons would be expected in the outermost electron shell of an atom with atomic number12?
The element is magnesium with the electronic configuration 2, 8, 2 and has 2 valence electrons.
