When a nucleus is unstable it has either too many or too few neutrons in the nucleus. This is what causes nuclear decay as the nucleus needs to have the correct ratio of neutrons to protons to be.
Different Types Radioactive Decay 11 Physics Classroom Beta Particle Decay
Radiation occurs when energy or parts of atoms are given off by radioactive atoms.
. An unstable nucleus results from too many or too few neutrons Which part of the periodic table indicates the number of energy levels in the electron cloud. An unstable nucleus results from too many or too few answer choices neutrons protons electrons radons Question 15 30 seconds Q. The reason nuclei become heavy with increasing atomic.
This is what causes nuclear decay as the nucleus needs to have the correct ratio of neutrons to protons to be. Many other rare types of decay such as spontaneous. If an element has too many or too few neutrons the element becomes unstable and will decay.
However in the case of there being too many neutrons surely the addition of neutrons should be adding extra strong nuclear force without extra electromagnetic repulsion which should make a nucleus more. The nucleus emits a beta particle and energy. Beta decay occurs when a nucleus is unstable because it has too many or too few neutrons relative to protons.
The nucleus emits a beta particle and energy. Add your answer and earn points. An unstable nucleus results from too many or too few 1 See answer Advertisement Advertisement meleaf3108 is waiting for your help.
Unstable isotopes decay through various radioactive decay pathways most commonly alpha decay beta decay or electron capture. Beta decay occurs when a nucleus is unstable because it has too many or too few neutrons relative to protons. Period What is the correct nuclear notation symbol for an isotope of carbon with 6 protons and 6 neutrons 12 C 6 Boron Carbon Nitrogen and oxygen are all members of the same period.
I understand that a nuclei with too many protons is unstable as the electromagnetic repulsion becomes too strong to be balanced by the strong nuclear force. In beta-plus decay a proton breaks down to a neutron and a positron and the positron is emitted from the nucleus. An unstable nucleus results from too many or too few Get the answers you need now.
When a nucleus is unstable it has either too many or too few neutrons in the nucleus. An unstable nucleus results from too many or too few Neutrons The nucleus of an atom has all of the following characteristics EXCEPT that it Contains nearly all of the atoms volume An atom is electrically neutral because The number of protons and electrons are equal. The nucleus of an atom contains protons and neutrons.
Meleaf3108 meleaf3108 22082018 Chemistry Secondary School An unstable nucleus results from too many or too few 1 See answer meleaf3108. Also why heavy nuclei are unstable. In beta-plus decay a proton breaks down to a neutron and a positron and the positron is emitted from the nucleus.
If you look at the periods rows with smaller numbers on the periodic table you will find that the number of protons and neutrons. The nucleus of an atom has all of the following characteristics EXCEPT that it answer choices is positively charged is very dense contains nearly all of the atoms mass contains nearly all of the atoms volume Question 16. If there are too many neutrons also obey the Pauli exclusion principle or too few neutrons for a given number of protons the resulting nucleus is not stable and it undergoes radioactive decay.
