How many electrons in atom with atomic number of 9 and atomic mass of 19 and is electrically neutral?
Since the atom is electrically neutral, the number of electrons must be the same as the number of protons in the atom, which is the definition of atomic number. Therefore, there are 9 electrons.
Fluorine's atomic number is 9 and its atomic mass is 19. How many neutrons does fluorine have?
Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.
What is the weight of the atom if an atom has 9 protons?
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
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 atomic mass of a number that have 8 protons and 9 neutrons?
The atomic mass of an atom can be calculated by adding the number of protons and neutrons together. In this case, an atom with 8 protons and 9 neutrons would have an atomic mass of 17 atomic mass units (amu).
What is the symbol of fluorine atom including its mass number and atomic number?
Symbol - F Atomic Number - 9 Mass Number - 19
An isotope of fluorine has a mass number of 19 and an atomic number of 9. how many protons are in this atom?
There are 9 protons in this fluorine atom because the atomic number (9) represents the number of protons in an atom.
How many protons are represented in an atom which has an atomic number of 9 and an atomis mass of 19?
An atom with an atomic number of 9 means it has 9 protons. The atomic mass of 19 indicates the total number of protons and neutrons in the nucleus, so if the atom has 9 protons, the remaining mass comes from neutrons (19-9=10 neutrons).
How many electrons in atom with atomic number of 9 and atomic mass of 19 and is electrically neutral?
Since the atom is electrically neutral, the number of electrons must be the same as the number of protons in the atom, which is the definition of atomic number. Therefore, there are 9 electrons.
A fluorine atom has 9 protons 10 neutrons and 8 electrons What are the mass number and atomic number for this atom?
The mass number is the sum of protons and neutrons, so it would be 9 (protons) + 10 (neutrons) = 19. The atomic number corresponds to the number of protons, which is 9 in this case.
How many protons neutrons electrons in atom of fluorine?
An atom of Fluorine has the atomic number 9 and the mass number 19 (rounded up). This means it has 9 electrons, 9 protons and (19-9) 10 neutrons. The proton and electron count are taken from the atomic number. The mass number - the atomic number gives the number of neutrons.
Fluorine's atomic number is 9 and its atomic mass is 19. How many neutrons does fluorine have?
Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.
An atom has a mass number of 9 and 5 neutrons What is its atomic number?
To find the atomic number, subtract the number of neutrons (5) from the mass number (9). The atomic number of the atom in question is 4.
An atom has a mass number of 9 and 5 neutrons. What is the atomic number?
The atomic number is 4
What is the mass number of a fluorine atom with 8 neutrons?
The atomic number is nine, because there are 9 protons. The mass number is 19, because an element does not have a charge, unless it forms to an ion. Therefore, if protons and neutrons have an amu of 1, the equation is as follows: Mass number (19)- Atomic number (9)= 10. There are 10 Neutrons and 9 protons.
What is the weight of the atom if an atom has 9 protons?
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
What do you get when you change the mass number of an atom?
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
