Feb 19, 2010 Atomic number is the number of protons. Therefore, there are 7 protons. In a neutral atom, number of electrons number of protons Therefore number of electrons 7 Number of protons number of neutrons atomic mass Or number of neutrons atomic mass number of protons 15 7 8 Ans: 7 protons, 8 neutrons, and 7 electronsNitrogen15 has a greater mass number than nitrogen14 because the atomic nucleus of nitrogen15 contains. 8 neutrons From its atomic number of 15, nitrogen-15 number of electrons

The 15 in nitrogen15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen15. 1 person found this useful

Nitrogen-15 number of electrons free

Subtracting the number of protons (7) from the element's mass number (14) makes it possible to determine the number of neutrons in the atom. Many nitrogen atoms have seven neutrons (147 7). Some atoms of nitrogen, however, have eight electrons. nitrogen-15 number of electrons So the number of electrons should also be 7. However, the number of neutrons can vary depending on the isotope. An isotope of nitrogen is a specific type of nitrogen. For example, you can have nitrogen14, which has 7 neutrons. Nitrogen15 would have 8 neutrons, nitrogen16 would have 9 neutrons and so on. What conclusions can be drawn about the existence of nitrogen14 and nitrogen15? A) They are isotopes of nitrogen and they contain the same number of protons and electrons but each contains a different number of neutrons 7 and 8 respectively. 7 electrons, 7 protons, and 7 neutrons. Nitrogen14 is actually an isotope of nitrogen, so right from the start, you can say that it is a neutral atom. Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. You know that nitrogen14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7. The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles.
