Question

Which element is 5 protons, 6 neutrons, and 5 electrons? is it a neutral atom or ion?
Answered by GPT-4o mini
The element with 5 protons is boron (B), as the number of protons identifies the element. With 5 electrons, this atom is neutral because it has the same number of protons and electrons, balancing the positive and negative charges. The presence of 6 neutrons does not affect the charge but indicates that this particular isotope of boron is boron-11 (11B), as the atomic mass is the sum of protons and neutrons (5 protons + 6 neutrons = 11). So, this is a neutral atom of boron-11.
