What element has 1 neutron and mass number of 2?
This is the isotope of hydrogen - deuterium.
What element has only 1 neutron?
The isotope helium-3 has only one neutron. It has 1 neutron, 2 protons and 2 electrons. You can get an atom's number of neutrons by subtracting its atomic number from its mass (nucleon) number.
What is the rule for determining the mass of an element?
The mass of an element is determined by adding up the number of protons and neutrons in its nucleus. This mass is generally expressed in atomic mass units (amu) where 1 amu is approximately equal to the mass of a proton or neutron.
What is the mass number for 1 proton and 0 neutrons?
The mass number is (by definition) the total sum of proton and neutron number in the nucleus of one particular isotope of an element.
What is the mass number of a neutron and a proton in hydrogen?
The mass number of a neutron is 1, as it contains one unit of mass. The mass number of a proton is also 1, as it contains one unit of mass. In hydrogen, the nucleus usually consists of one proton, so the mass number of a proton in hydrogen is 1.
How do you determine the number of neutron's in an atom of a given element?
Atomic Mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
What element has 1 neutron and 2 electrons?
The mass number is the sum of the number of neutrons and protons. If we already know that there is one neutron and the mass number is two, then that means there is one proton. Any atom with one proton is hydrogen. This particular isotope is called deuterium.
What is the atomic number the atomic mass and the number of neutrons of the element hydrogen?
The 'standard' hydrogen atom has atomic number 1, atomic mass 1, no neutrons. Although there are 2 other isotopes of hydrogen: - (cant confirm name) which has atomic mass 2 and 1 neutron. - (cant confirm name) has atomic mass of 3 and 1 neutron. All isotopes have atomic number 1.
How does the mass number of an atom change when its nucleus absorbs a neutron?
Essentially the 3 basic parts to an atom are a Proton, Neutron and an Electron. Protons have a unit of mass and a positive charge Neutrons have a unit of mass and a neutral charge Electrons have no unit of mass and a negative charge. When a neutron breaks off from another atom it becomes a free radical that is then absorbed by the receiving atom because it would have a spare neutron space because the number of neutrons must be identical to the number of protons otherwise the atom will radioactivity decay. Essentially the mass number changes because the neutron has a mass.
What element has 1 amu with no charge?
The element hydrogen has a mass of approximately 1 atomic mass unit (amu) and is typically shown as having no charge in its most common form.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Is unium hydrogen?
Yes, it is one of the hydrogen isotopes. This name is sometimes used to distinguish H(1) isotope from H(2) isotope which is commonly called deuterium. The H(3) isotope's name is tritium. Explained: uni = 1 = 1 proton = 0 neutron = mass number (1) = 'normal hydrogen' deutero = 2 = 1 proton = 1 neutron = mass number (2) = 'heavy' hydrogen tri = 3 = 1 proton = 2 neutron = mass number (3)
