What else can I help you with?
What If you add a mass of 3.7 g to a mass of 9.495 g the sum with the correct number of significant digits is?
It is 13.2 grams.
The sum of any number and 0 is the number?
The sum of any number and 0 is the original number.
What is the sum of a number and zero?
If you add zero to any number, the sum is the same number you started with.
The sum of a number and 2?
let the number be n, then the sum of the number and 2 is n+2
The sum of a number plus 3 is squared is 11 more than the sum of the number plus 2 when squared What is the number?
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
How do you determine sum of subatomic particles?
The mass number is the sum of protons and neutrons in the atomic nucleus.
What is the sum of the masses of the positively charged subatomic particles are called what?
You think probably to mass number; the mass number is the sum of protons and neutrons.
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
How do you calculate subatomic particles in isotopes?
To calculate the number of subatomic particles in isotopes, you need to know the atomic number (number of protons) and mass number (sum of protons and neutrons) of the isotope. Subtract the atomic number from the mass number to find the number of neutrons. The number of electrons will be equal to the number of protons if the atom is neutral.
How many subatomic particles are in a symbol of a nuclide?
Symbols of nucldes doesn't contain symbols of subatomic particles. But: the atomic number is equal to the number of neutrons. Example: 235 92U (the fissile isotope of uranium) - 235 is the mass number (sum of protons and neutrons) - 92 is the number of protons and electrons
How many total number of particles present in one atom?
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
What subatomic particles contribute to the mass of?
The atomic mass is the sum of the number of protons and the number of neutrons found in each atom of that element (electrons do not contribute). They are sometimes seen on periodic tables to have a decimal in the atomic number, this is for elements with more than one common isotope (an isotope of an element is the same number of protons but with a different number of neutrons), in which case an average of the common isotopes can be used.
What can be said about the sum of the masses of the subatomic particles in an atom's nucleus?
The sum of the masses of the subatomic particles in an atom's nucleus is less than the total mass of the nucleus. This is because some mass is converted into binding energy to hold the nucleus together via Einstein's mass-energy equivalence principle (E=mc^2).
How many subatomic particles are in the element xenon?
The "subatomic" particles in atoms are usually considered to be only protons, neutrons, and electrons, although these may contain sub-subatomic particles such as quarks and gluons. Every atom of xenon contains 54 protons and 54 electrons, because 54 is the atomic number of xenon. Every atom of xenon also contains neutrons. The lightest naturally occurring and radioactively stable isotope of xenon is Xe-124. Since the mass number is the sum of protons and neutrons, the total of protons, electrons, and neutrons for this isotope is 124 + 54 or 178. The number of particles for any other isotope of xenon may be found by adding the mass number to the atomic number.
What are the subatomic particles for bromine-80?
Bromine-80 has 35 protons, 35 electrons, and 45 neutrons. This information is determined by the atomic number (number of protons) and mass number (sum of protons and neutrons) of the isotope.
What is the sum of protons and neutrons known as an element?
The sum of protons and neutrons in an atom is known as the atomic mass or mass number of an element. It is typically shown as the whole number next to the element's symbol in the periodic table.
Why does carbon C have a larger atomic mass than boron?
Carbon has a larger atomic mass than boron because it has more protons, neutrons, and electrons. The atomic mass of an element is the sum of the protons and neutrons in the nucleus of an atom, and carbon has more of these subatomic particles compared to boron.
