The number of protons in an element is the same as its atomic number. The element with atomic number 7 is Nitrogen.
If you look in the related link below you will see that all the elements atomic numbers are listed here. This will help you with further homework questions.
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
Nitrogen-14 has 7 protons, 7 electrons, and 7 neutrons. Nitrogen-15 has 7 protons, 7 electrons and 8 neutrons. So, the only way they differ is in the NUMBER OF NEUTRONS.
Number of protons + Number of neutrons = Mass number(number of nucleons)
7 protons, 7 neutrons and 7 electrons
Atoms having the same number of protons and neutrons make up the same element.
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
The element with 7 electrons, 7 protons, and 8 neutrons is nitrogen-15 (15N).
7
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
Seeing the number of protons, I would guess nitrogen.
A neutral nitrogen atom has 7 protons, 7 neutrons, and 7 electrons. If it is electrically charged, the number of electrons will be different. If it is an isotope of nitrogen other than the most common (N-14), the number of neutrons will be different. Protons = Atomic Number Neutrons = Atomic Mass - Protons Electrons = Protons Atomic number is the amount of protons in element.
A positively charged ion of oxygen
The element that has 8 protons and 8 neutrons is oxygen.
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
carbon or boron
It is about neutrons and protons. The total of neutrons and protons.
Neon has 10 protons and 9 neutrons.
