How many protons are present in an atom of Be 9?
There are 4 protons in 9Be. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying Be-9) is unneeded.
How many protons electrons and neutrons are in an atom with an atomic number of seventy nine and an atomic mass of one hundred ninety seven?
59 = # of protons and # of electons 59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons: 96 - 59 = 37 neutrons
What Atomic number of element has 9 protons and 10 neutrons?
The atomic number of an element is equal to the number of protons in its nucleus. Given that the element has 9 protons, its atomic number is 9. Therefore, the element in question is fluorine (F), which has an atomic number of 9.
The atomic mass of an element whose atoms consist of eight protons nine neutrons and eight electrons is what?
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
What is atomic number nine?
Fluorine is a meta element. Atomic number of it is 9.
Number of protons in fluorine atom?
An atom's atomic number gives us its number of protons. Fluorine's atomic number is 9. Thus, it has 9 protons.
How many protons are found in a atom of fluorine?
The atomic number of fluorine is 9. So there are 9 protons
How many protons are present in an atom of Be 9?
There are 4 protons in 9Be. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying Be-9) is unneeded.
How many electrons are in a neutral atom of 19F?
A neutral atom of fluorine-19 (19F) has 9 protons and 9 electrons. This is because the number of protons determines the element's identity, so fluorine always has 9 protons, and in a neutral atom, the number of electrons is equal to the number of protons.
How many protons electrons and neutrons are in an atom with an atomic number of seventy nine and an atomic mass of one hundred ninety seven?
59 = # of protons and # of electons 59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons: 96 - 59 = 37 neutrons
What Atomic number of element has 9 protons and 10 neutrons?
The atomic number of an element is equal to the number of protons in its nucleus. Given that the element has 9 protons, its atomic number is 9. Therefore, the element in question is fluorine (F), which has an atomic number of 9.
What is the atomic number of an element whose atoms have 9 protons and 10 neutrons?
The atomic number is the number of protons. It is also the number of electrons. The atomic mass equals the protons and neutrons together/weight of the nucleus. So, the atomic number would be nine, because there are 9 protons. The atomic mass would be around 19, because there would be 9 protons and 10 neutrons in the nucleus. The element you are talking about is actually Fluorine, and on the periodic table it says that the atomic mass is 18.9984032. This is because the atomic mass is usually never an exact amount. You can round this decimal place to 19, anyway.
What atom has the atomic number of seventy-nine?
Gold
What is fluorine's number of neutrons?
Neutrons have the same mass as a proton but lack an electrical charge. The number of neutrons can be found by subtracting the atomic number, or number of protons in the atom, from the atomic weight. This is calculated this way because the atomic weight represents both the number of protons and neutrons. Fluorine's atomic number is 9 and its atomic weight is 18.998, so 18.998-9= 9.998. Consequently, 9.998 is fluorine's number of neutrons.
The atomic mass of an element whose atoms consist of eight protons nine neutrons and eight electrons is what?
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
Which element's atoms contains twenty nine protons?
It is element 29 on the periodic table. The elements in the periodic table are arranged according to increasing atomic number. The atomic number is the number of protons in the element's atoms.
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.
