What is the name of an atom that has 19 protons 19 electrons and 20 neutrons?
An atom with 19 protons and 19 electrons is potassium (K), as the number of protons defines the element. The presence of 20 neutrons gives it an atomic mass of 39 (19 protons + 20 neutrons). This specific isotope of potassium is potassium-39 (K-39).
What is the number of nuetrons in a potassium atom?
The most common isotope is 20
An atoms of potassium has atomic mass of 39 amu and an atomic number it therefore has neutrons in its nulces?
An atom of potassium with an atomic number of 19 has 20 neutrons in its nucleus. This can be determined by subtracting the atomic number from the atomic mass (39 - 19 = 20).
What is the atomic mass of an atom that contians 19 protons 19 electrons and 20 neutrons?
The atomic mass of the isotope potassium-39 is 38,963 706 68(20).
An atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of what?
To find the atomic mass, subtract the atomic number (protons) from the mass number (protons + neutrons). Atomic mass = Mass number - Atomic number Atomic mass = 19 - 9 Atomic mass = 10amu So, an atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of 10 atomic mass units (amu).
What is the mass number of an atom with 19 protons and 20 neutrons?
The element is potassium. Atomic mass is 38.
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 name of an atom that has 19 protons 19 electrons and 20 neutrons?
An atom with 19 protons and 19 electrons is potassium (K), as the number of protons defines the element. The presence of 20 neutrons gives it an atomic mass of 39 (19 protons + 20 neutrons). This specific isotope of potassium is potassium-39 (K-39).
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.
What is the number of nuetrons in a potassium atom?
The most common isotope is 20
How many protons electrons and neutrons does an atom of potassium have?
An atom of potassium has 19 protons, 19 electrons, and typically 20 neutrons.
What is the mass number and symbol of an atom that contains 19 protons 19 electrons and 20 neutrons?
The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
An atoms of potassium has atomic mass of 39 amu and an atomic number it therefore has neutrons in its nulces?
An atom of potassium with an atomic number of 19 has 20 neutrons in its nucleus. This can be determined by subtracting the atomic number from the atomic mass (39 - 19 = 20).
What is the total number of neutrons in the nucleus of a K 37 atom?
A potassium-37 (K-37) atom typically has 20 neutrons in its nucleus. This is because the number of neutrons is calculated by subtracting the atomic number (which is 19 for potassium) from the mass number (which is 37 for K-37).
What is the atomic mass of an atom that contians 19 protons 19 electrons and 20 neutrons?
The atomic mass of the isotope potassium-39 is 38,963 706 68(20).
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
An atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of what?
To find the atomic mass, subtract the atomic number (protons) from the mass number (protons + neutrons). Atomic mass = Mass number - Atomic number Atomic mass = 19 - 9 Atomic mass = 10amu So, an atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of 10 atomic mass units (amu).
