What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
The nucleus of a radium 226 atom is unstable which causes the nucleus to?
Decay
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
Magnesium

Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What happens to a nucleus of an unstable atom?
the unstable nucleus will decay into smaller, stable particles.
The nucleus of a radium 226 atom is unstable which causes the nucleus to?
Decay
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
What it means when an element is radioactive?
Radioactive elements have unstable nucleii. When an unstable nucleus decays it emits energy in the form of electromagnetic waves and heavy particles and in the process forms new nucleii.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
Magnesium
What is the term for an atom that has an unstable nucleus?
radioisotope
What is radioactive in physics?
the unstable nucleus of an atom
Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
Is radioactivity caused due to unstable nucleus?
Yes.
