NEED ANSWER NOW
1.A new element was discovered by Mr. Carney and was called Carneydium. It had an atomic mass of 430 and an atomic number of 120. Explain the atomic composition of Carneydium.
2. Explain how a Mixture, Molecule and Compound are different. Also, provide examples of each please. This question is worth 3 points, .5 for each requirement.
3.Use the periodic table to identify the element given the clues below:
This element is in period 5 and does not react with other elements
4.Use the periodic table to identify the element given the clues below:
This element is a metalloid with an atomic mass less than Carbon.
5. In most cases (Bohrium, #107 is an exception) the atomic mass increases as the elements increase in atomic number. This makes sense, as we are adding a Proton, which has mass. But why might Bohrium go down in mass if we are adding one proton?
6.Carneydium (Mr. Carney's made up element) is a metal. Weglovium (A made up element named after Mr. Wegley) is a non-metal. Even though they are not real, infer how they may be different if they were real.
