The atomic number refers to the number of protons in an element. The mass number can be used to indicate the number of neutrons because both protons and neutrons have a mass of about 1. An oxygen atom has 8 protons and 8 neutrons.
Atomic number of oxygen: 8After the IUPAC Tables, 2009 the atomic weight of oxygen is[15,99903; 15,99977].The abridged conventional atomic weight is (also after the IUPAC Tables, 2009) 15,999; following the IUPAC tradition the correct expression is atomic weight, not atomic mass.
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
Tungsten's atomic number is 74, which means it has 74 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 184 (atomic mass) - 74 (atomic number) = 110 neutrons in Tungsten.
There are 120 neutrons in 202Hg. Mercury-202 has an atomic number of 80, which means it has 80 protons. Neutrons can be calculated by subtracting the atomic number from the atomic mass.
The mass number of Potassium is 39 which means it has 20 neutrons.
The atomic number of oxygen is 8, which means that there are 8 protons in the nucleus of an oxygen atom. Mass number = protons + neutrons, therefore neutrons = mass number - protons = 16 - 8 = 8 neutrons.
Oxygen has the atomic number 8 and an atomic mass of 16.That means it has 8 protons, 8 electrons, and 8 neutrons.Rules for Calculating Protons, Electrons, and Neutrons in Uncharged CompoundsProtons = atomic numberElectrons = protons = atomic numberNeutrons = atomic mass - protonsRemember, if you have a charged ion, the number of electrons will be different.Oxygen is normally found as O2. A molecule of O2 will have 16 protons, 16 electrons, and 32 neutrons.
Atomic number of oxygen: 8After the IUPAC Tables, 2009 the atomic weight of oxygen is[15,99903; 15,99977].The abridged conventional atomic weight is (also after the IUPAC Tables, 2009) 15,999; following the IUPAC tradition the correct expression is atomic weight, not atomic mass.
Oxygen has a mass number of 16.00 with atomic number 8 which means there are 8 electrons and 8 protons. The number of neutrons is always equal to the mass number- the atomic number. In this case it is 16 - 8= 8. Protons: 8 Neutrons: 8 (for isotope O16 the most common) Electrons: 8
oxygen has atomic number 8. It means that there are 8 protons (positively charged) adn 8 electrons (negatively charged). Since the number of positive charges and negative charges is equal, they both nullify each other and atom become electrically stable. The number of neutrons don't matter as they are neutral in charge.
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
Tungsten's atomic number is 74, which means it has 74 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 184 (atomic mass) - 74 (atomic number) = 110 neutrons in Tungsten.
There are 120 neutrons in 202Hg. Mercury-202 has an atomic number of 80, which means it has 80 protons. Neutrons can be calculated by subtracting the atomic number from the atomic mass.
Palladium has 60 neutrons. It has an atomic number of 46, which means it has 46 protons. To find the number of neutrons, you subtract the atomic number (protons) from the atomic mass (protons + neutrons). Palladium's atomic mass is approximately 106.4, so 106.4 - 46 = 60 neutrons.
Cesium-133 has an atomic number of 55, which means it has 55 protons in its nucleus. Since the atomic number represents the number of protons, the number of neutrons in an atom of cesium-133 can be calculated by subtracting the atomic number from the atomic mass.
Oxygen has an atomic number of 8. This also means that it has 8 protons in its nucleus.
The number of neutrons in an atom of argon is typically 22. Argon has an atomic number of 18, which means it has 18 protons in its nucleus. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is approximately 40 for argon.
