The elements lithium, sodium, and potassium O have the same number of neutrons are isotopes of each other are in the same period of elements are in the same group have the same mass number
Atoms and Isotopes 1 Activity: Atoms and Isotopes Why? Atoms and isotopes are identified by the numbers of protons, electrons, and neutrons that they contain The number of protons, electrons, and neutrons in atoms determines the chemical properties of the elements .A knowledge of the number of protons and electrons in an atom will help you understand how atoms combine to form molecules Identify the composition of atoms in terms of protons, neutrons, and electrons Use atomic symbols to represent...
which of the following statements about isotopes is false Which of the following statements about isotopes is false? Select one: O a. An isotope with more neutrons will have a greater mass than an isotope with fewer neutrons. O b. All of the above are true. c. Isotopes are atoms with same number of protons but different numbers of neutrons. d. Isotopes are atoms with the same atomic number but different mass numbers. O e. Most elements naturally have more...
The atomic number of lithium is 3. How many neutrons does an atom of lithium have if it is represented by the symbol shown below? 1. 7Li O A. 2 neutrons O B. 13 neutrons O C.4 neutrons O D.7 neutrons
The elements argon and calcium have isotopes 40Ar and 40Ca. Both of these isotopes are naturally occurring and comprise >90% abundance. What isotope of Ca will the same number of neutrons as there are in 40Ar?
II. Isotopes Atoms of a given element all have the same number of protons and electrons, but can have different numbers of neutrons. Versions of the same element with differing numbers of neutrons are call isotopes. The symbol for an isotope is AX Where: A is the mass number (number of protons plus neutrons) Z is the atomic number (number of protons) X is the symbol for the element 2. Show the isotope symbol for the isotope of Fe with...
Copper has two stable isotopes, Cu and electrons in Copper-65? Cu. How many protons, neutrons and 29 protons, 34 neutrons and 29 electrons 65 protons, 29 neutrons and 65 electrons 29 protons, 36 neutrons and 29 electrons 36 protons, 29 neutrons and 36 electrons Which statement is FALSE about electrons and the energy levels they occupy in the structure of an atom? While the mass of an electron amounts to almost nothing they can absorb and emit significant amounts of...
