The atom's protons is the same as its electrons, which is 17. The atomic number is the same as the number of protons, so the atomic number is 17. To get the neutrons, you subtract 17 from 35 because 35 is the amount of protons and neutrons, and we already found out that there are 17 protons. So there are 18 neutrons.
PROTONS: 17
ATOMIC NUMBER: 17
NEUTRONS: 18
15 protons. Atomic number determines the number of protons which the element has
All silicon atoms have 14 electrons and 14 protons. That is a rule that every silicon atom must follow. On the periodic table, the number next to the atom is the number of electrons/protons in an atom (silicon is the 14th element listed on the periodic table, hence the 14 electrons and 14 protons). The number "29" is the number of protons and neutrons together. This number can change with changing isotopes. So, if every silicon atom must have 14 protons, and 29 is the number of protons and neutrons together, so the number of neutrons must be 29 minus 14. Final: 14 protons 14 electrons 15 neutrons
There are 8 neutrons, 7 protons, and 7 electrons. Atomitc number is always tells how many protons there are. We consider protons and neutrons to have a weight of 1. There are 7 protons, so we take the weight and subtract it from 15 to get how many neutrons we have ( which is 8). Because the atom is neutral ( no charge) there has to be the same amount of electrons as there are protons ( which is 7).
Nitrogen is a non metal element. Atomic mass of it is 14.
the number of protons equal the number of electrons. the element phosphorus has 15 electrons on its outer rings. the energy levels are 2,8,and 5. this element also has 15 protons and neutrons. written by: 8th grade student Kirby
The element is sulfur and the isotope is 16S31
An atom with 15 protons, 15 neutrons, and 15 electrons.
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
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.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
13 protons means it must be aluminum (Al). 15 neutrons means its atomic mass will be 28. This is not aluminum's most abundant isotope, but it is still aluminum.
The phosphorus atom has 15 protons and electrons and 16 neutrons.
There are 15 protons and 16 neutrons in the phosphorus atom. The atomic number, which is at the top of the square, represent the number of protons. In a neutral atom, there are the same amount of protons as well as electrons so there are 15 protons and 12 electrons. You can find the number of neutrons by subtracting the atomic number from the atomic mass and round to the nearest whole number. In this case, the atomic number would be 15 and the atomic mass is 31. 31 minus 15 is 16 neutrons total.
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.
15 protons. Also usually 15 electrons and 15 neutrons.
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
