match the correct term with the definition question 1 options: the neutrally charged element in the nucleus of an atom the number of protons an atom has an atom of an element that has a different number of neutrons that the standard atom of that element protons + neutrons in the nucleus of an atom the positive particle in the nucleus of an atom 1. atomic mass 2. neutron 3. atomic number 4. proton 5. isotope identify the atomic number and atomic mass of the following element question 2 options: number: 35.453 mass: 17 number: 17 mass: 18 number: 18 mass: 17 number: 17 mass: 35.453 which atomic particle gives an atom gives it it’s chemical properties? question 3 options: protons isotopes neutrons electrons all atoms of an element always have the same number of question 4 options: neutrons electrons protons electrons how many protons, neutrons, and electrons does a neutral atom of this element have? (round atomic mass to nearest whole number) question 5 options: protons: 13 neutrons: 13 electrons: 13 protons: 13 neutrons: 14 electrons: 13 protons: 27 neutrons: 13 electrons: 14 protons: 14 neutrons: 27 electrons: 13 a neutral atom of an element has the same number of and question 6 options: protons and electrons neutrons and electrons protons and neutrons which of the following is are isotopes of carbon? (carbon has an atomic number of 6 and an atomic mass of 12) question 7 options: only b is an isotope a and c are isotopes a and b are isotopes b and c are isotopes

99pts. i can't find isotope, pottasium-15 or k-15. is this even possible, i have a fill-in-the-blanks worksheet with a table like example: element name: nitrogen-20 symbol: n-20 atomic number: 7 atomic mass: 20 charge: 0 protons: 7 neutrons: 13 electrons: 7 i remember finding the isotope number, nitrogen-20 by adding the protons and neutrons, then i get a new atomic mass. but on here pottasium-15 is confusing! what neutrons do i add from 19 protons to get 15? sometimes the teacher throws in impossible problems.
