- Help with the following questions???
- How would you determine the total number of electrons found in an atom?
- What is the difference between empirical, molecular, and structural formulas?
- Protons and neutrons are located in the nucleus of what?
- What are atoms with the same number of protons but different number of of neutrons called?
- Is the Bohr model valid?
- What is the electronic arrangement for an atom with FOUR electrons?
- Are electrons electrically neutral or are they charged?
- What is true of all atoms?
- The mass of an atom may be determined by adding the masses of the protons and neutrons in the nucleus and then subtracting the mass defect. Why is it unnecessary to include the electrons when determining the mass of an atom?
- How do you find the protons, neutrons, and electrons for a Bromine (#1^-#) anion with a mass number of 80?
- What is the mass of an electron in amu?
- Do the neutrons in the atom's nucleus keep two or more protons from moving apart?
- What are the components of an atom?
- If the electrons are removed from a helium atom, what remains? What is it called?
- Multiply the atomic number of hydrogen by the number of electrons in mercury, which has an atomic number of 80. What is the result?
- What did Louis deBroglie do?
- What is the name of the scientist who first proposed that atoms have nucleus?
- What two particles have approximately the same mass?
- If an element has atomic number 9 and atomic mass 19, how many neutrons will it have?
