12 protons and no electrons
Eukayotic cells have a contained nucleus
Chromatin material is contained within the nucleus.
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
None. The nucleus IS and organelle.

DNA is contained in the nucleus and everyone's genetic code is different..
The mass of an atom is primarily contained in its nucleus, which is made up of protons and neutrons. Electrons, which have a much smaller mass compared to protons and neutrons, occupy the space surrounding the nucleus.

Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
Sodium is an element itself, it has no elements inside.
It has DNA that is not contained within the nucleus.
