Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
What is the change in an mass number after alpha decay?
The mass number decreases by 4 and the atomic number decreases by 2 after alpha decay. This is because an alpha particle consists of 2 protons and 2 neutrons, which are emitted during the decay process.
How is the mass number of an element affected when it decays by ejecting an alpha partical?
The mass number of an element decreases by 4 when it decays by ejecting an alpha particle. This is because an alpha particle has a mass number of 4 and atomic number of 2. The atomic number of the element also decreases by 2.
What decay decreases atomic mass by 1?
Beta decay decreases atomic mass by 1. In beta decay, a neutron in the nucleus is converted into a proton, releasing a beta particle (an electron) and an antineutrino. This results in an increase of the atomic number by 1, while the atomic mass remains the same.
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
How does force affects mass and acceleration?
Increasing force increases acceleration but increasing mass decreases acceleration.
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
Which scientist arranged the elements in order of increasing atomic number rather than increasing atomic mass?
Henry Moseley arranged the elements in order of increasing atomic number rather than increasing atomic mass, which led to the modern periodic table.
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
What happens to the mass and atomic number when there is an alpha decay?
The mass decreases by 4 units and the atomic number by two units.
What is the change in an mass number after alpha decay?
The mass number decreases by 4 and the atomic number decreases by 2 after alpha decay. This is because an alpha particle consists of 2 protons and 2 neutrons, which are emitted during the decay process.
How is the mass number of an element affected when it decays by ejecting an alpha partical?
The mass number of an element decreases by 4 when it decays by ejecting an alpha particle. This is because an alpha particle has a mass number of 4 and atomic number of 2. The atomic number of the element also decreases by 2.
How did mendellev design the periodic table?
Mendeleev designed the periodic table by increasing atomic mass. But it was later changed to increasing atomic number.
What decay decreases atomic mass by 1?
Beta decay decreases atomic mass by 1. In beta decay, a neutron in the nucleus is converted into a proton, releasing a beta particle (an electron) and an antineutrino. This results in an increase of the atomic number by 1, while the atomic mass remains the same.
Mendeleev arranged the elements in his periodic table in order of?
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass while also grouping elements with similar properties together. His periodic table laid the foundation for the modern periodic table we use today.
