What else can I help you with?
Atoms of the same element that differ in the number of neutrons they contain are known as?
they are known as isotopes. Dont ask people to do your homework
What is 1 proton 2 neutrons?
<P>proton + neutrons give you a nucleon. the nuceon(or protons +neutron) give you the overall mass of the atom. the mass of electrons is not included, i dont even think that it has mass at all. Hope you're answered?</P>
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 an isotope Give an example?
An isotope is an atom of a given element with a different mass. this means it must have a different number of neutrons, as changing the amount of protons would change the element. in short, an isotope is an atom with a special number of neutrons. eg. normal hydrogen- 1 H 1 deuterium (hydrogen with a neutron) 2 H 1 if you dont understand what im talking about just wiki it.
How many protons electrons and Neutrons does the element Silicon have?
Atomic number 14 it has 14 protons it has 14 electrons, provided it is a silicon atom and not an ion with -4 charge neutrons here are a variable. i dont know the percentages of each ion, but the atomic mass is 28.08, that rounds to 28, subtract 14 and silicon most commonly has 14 neutrons
Why do electric eels produce electricity if electricity and water dont mix?
They release neutrons and protrons and when in contact with a human in the water it creeats an electrict energy field or force received by the flesh
How many protons electrons and neutrons are there in an atom that has an atomic number of 8 and a mass of 15?
Learn that the atomic number means the number of protons. The mass number is the number of protons and the number of neutrons. So if we take the number of protons from the mass number then we get the number of neutrons that are present (mass umber - atomic number = number of neutrons). in this case 15 - 8 = 7. Since you dont mention there is any charge on the atom ill assume that its charge is neutral. For an atoms charge to be neutral then the positive charges from protons must equal the negative charges from electrons and vica versa. So for this to be the case with 8 protons then we must have 8 electrons.
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 happens to the atomic number and the atomic mass has the same number of protons but different number of neutrons?
i dont think this question makes sense
How many neutrons are in an atom with an atomic number of 3?
The elemnt with atomic number 3 is Lithium. There is no easy way of determining how many neutrons are in an atom, in Lithium there are two stable isotopes, 6Li with 3 neutrons and 7Li with 4. The most common is 7Li. If you ever have to guess because you dont have access to Wikipedia or a table of the elements which shows the different isotopes, there are often the same number of neutrons as protons in stable isotopes.
What number sentence is equal to 27 plus 18?
i realy dont know
How can you tell how many neutrons are in an element?
The number of neutrons in an element is determined by subtracting the atomic number from the atomic mass number rounded to the nearest whole number. On the other hand, very few atoms are abnormal and have a different amount of neutrons than other atoms of the same element. These are called isotopes and are indicated by a number following the element symbol (eg. C-14). This is a radioactive isotope of carbon that has six protons based on the atomic number and two more neutrons than normal--8. (8+6=14). Finally, the reason that the atomic mass units end in decimals is that this is just an average weight. The isotopes can either bring this number up or down. atomic number [ 6 ] symbol [ C ] mass (atomic mass units (amu)) [ 12.01 ]
Is x equals 3 is relation?
no because if you dont have a number after the X, it wont equal anything.

What element has 57 protons and 73 neutrons?
I dont think there is one.
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).
