- Atoms that vary in the number of neutrons found in their nuclei are called _____________. ions neutrons neutral atoms isotopesAn isotope of sodium (Na) has a mass number of 22. How many neutrons does it have? a. 11 b. 12 c. 22 d. 44The mass number of an atom depends primarily on the number of protons and neutrons. positrons. neutrons and electrons. protons and electrons.
- The number of protons in a neutral (no charge) atom equals the number of O elements. electrons. O ions. isotopes. neutrons minus electrons.Which of the following is not a fundamental subatomic particle that forms elements? Which of the following is not a fundamental subatomic particle that forms elements? electrons protons nucleus neutronsA nitrogen isotope with an atomic mass of 15, and an atomic number of 7, must have: 7 neutrons and 8 electrons 8 neutrons and 7 protons 7 electrons and 8 protons 8 protons and 7 neutrons 7 protons and 8 electrons
- Knowing the atomic mass of an element allows inferences about which of the following? the number of protons plus neutrons in the element the number of protons plus electrons in the element the number of electrons in the element the number of protons in the elementWhy the Number of Electrons Matter Since we know each element as a defined number of protons, we can also use that number to determine the number of electrons, assuming the element has no charge. Let’s write some out: ELEMENT NUMBER OF PROTONS NUMBER OF ELECTRONS C A B O C D Al E F Na G H Si I JElement Atomic Number Mass Number Number of Protons Number of Neutrons Number of Electrons Carbon-12 12 6 Nitrogen-14 7 7 Chlorine-35 35 17 Oxygen-16 8 Carbon-14
