What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
How many neutrons does Boron have if the mass number is 10?
Boron typically has 5 neutrons, as the mass number is the sum of the protons and neutrons in the nucleus. In this case, with a mass number of 10, and Boron having 5 protons (atomic number 5), the number of neutrons is 5 (10 - 5 = 5).
What is the symbol and atomic number for an isotope with an mass number of 5 containing 10 neutrons?
The symbol for the isotope would be B and the atomic number would be 5, as the mass number is the sum of the protons and neutrons in the nucleus, so in this case: 5 protons + 10 neutrons = mass number 15.
What is the mass of an atom that has 10 protons 13 neutrons 10 electrons?
The mass number of this atom is 23, the sum of the number of protons and neutrons.
Calculate the number of protons of the atom whose mass number is 19 and whose number of neutrons is 10?
To find the number of protons, you need to subtract the number of neutrons from the mass number. In this case, the atom has a mass number of 19 and 10 neutrons, which means the number of protons is 19 - 10 = 9 protons.
What is the number of 6 neutrons from a mass number of 10?
To find the number of neutrons in an atom, subtract the atomic number from the mass number. Therefore, for an atom with a mass number of 10 and an atomic number of 4, there would be 6 neutrons (10 - 4 = 6).
What is the number of neutrons in an atom with atomic number 12 and mass number 22?
Number of neutrons = Mass number - Atomic number = 22 - 12 = 10
An atom that has 11 neutrons and an atomic number of 10 has a mass number of what?
The mass number of this atom is (10 + 11 =) 21.Remember:Mass number is the sum of (the number of) neutrons (= 11) and protons.Atomic number is equal to the number of protons (= 10)This atom is the least abundant isotope of neon, 2110Ne (< 0.3%)
How many protons neutrons and electrons are in a neutral atom of neon if its atomic number is 10 and its mass number is 22?
A neutral atom of neon with atomic number 10 has 10 protons and 10 electrons. The mass number of 22 indicates the total number of protons and neutrons combined. Since the atomic number is 10, the number of neutrons is 22 - 10 = 12.
What percent of the mass of the isotope boron-10 are neutrons?
Boron-10 isotope has 5 neutrons out of a total of 10 particles, so the percentage of neutrons in boron-10 is 50%.
An atom that contains 15 protons and 10 neutrons within its nucleus will have an atomic mass of?
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
