If an element has 8 protons and 8 neutrons in its nucleus and 8 electrons revolving around the nucleus What is the atomic number and atomic mass of this element?
In neutral atoms (with the same number of protons and electrons), the number of protons and electrons equal the atomic number. If our atom has 9 electrons, is neutral, and therefore has 9 protons, it is element #9: Flourine, which has an atomic mass of 19: 9 protons plus 10 neutrons.
How many neutrons does F-19 have?
The atomic number of Florine is 9 so it has 9 Protons in its nucleus. As the mass number of an atom is essentially the mass of the nucleus and as the mass of each Proton or Neutron is 1 this means that if there are 9 Protons there must be 10 Neutrons present to make up a mass number of 19.
How many neutrons does potassium have'?
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39. Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
Which element on the periodic table has 19 protons?
The element with 19 protons is potassium, which is represented by the symbol K on the periodic table.
How many neutrons are in oxygen-19?
Potassium has several known isotopes, some of which are stable or at least very long lived. 19K is not one of hem. 32K (13 neutrons) to 55K (36 neutrons) have been identified. The stable ones are 39K and 41K. Should an isotope 19K be created, it would have no neutrons. It would decay by electron capture (most likely) to something like fluorine. With a great number of gamma photons emitted as well.
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
What is the mass number of an element has 19 protons 19 electrons and 20 neutrons?
19
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
What is the mass number of CI if it has 19 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Chlorine (Cl) has an atomic number of 17, so it has 17 protons. If it has 19 neutrons, then the mass number would be 17 (protons) + 19 (neutrons) = 36. Therefore, the mass number of this chlorine atom is 36.
How many neutrons occur in potassium with a mass number of 39?
Potassium with a mass number of 39 has 20 neutrons. The mass number of an element is the sum of its protons and neutrons. Since the atomic number of potassium is 19 (number of protons), the number of neutrons can be calculated by subtracting the atomic number from the mass number.
Mass number of 19?
The mass number of an atom is the total number of protons and neutrons in its nucleus. For an atom with a mass number of 19, it would have 19 total protons and neutrons combined. This atom could be potassium-40 (19 protons and 21 neutrons) or calcium-40 (20 protons and 20 neutrons), for example.
What is the mass number of an atom with 19 protons and 20 neutrons?
The element is potassium. Atomic mass is 38.
How many nuetrons are in fluorine with a mass number of 19?
Fluorine has an atomic number of 9, which means it normally has 9 protons. With a mass number of 19, the total number of protons and neutrons in fluorine is 19. Therefore, subtracting the atomic number of 9 protons gives us 10 neutrons in fluorine with a mass number of 19.
What is the mass number for fluorine -19?
Fluorine is a non metal element. Atomic mass number of it is 19.
What element has 9 electrons 9 protons and 10 neutrons?
The element is Neon and the isotope is 10Ne19
What is the mass number of a fluorine atom?
Fluorine is a non metal element. Mass number of it is 19.
How many protons does potassium 39 have?
The mass number, the number that follows the hyphen at the end of an element name, is the sum of the atomic number of the element and the number of neutrons in each atom of the isotope specified by mass number. The atomic number of potassium is 19; therefore, potassium-39 contains (39 - 19) or 20 neutrons.
