First of all there is NO reason for the plural form of this question, because every element has only ONE unique atomic number with ONE unique symbol. In this case 86Ra
Radium is a radioactive chemical element which has the
symbol Ra and
atomic number 88 (group II, period 7 in the PS).
Its appearance is almost pure white, but it readily oxidizes on exposure to air, turning black. Radium is an alkaline earth metal (like Ca and Ba).
Ra is found in trace amounts in uranium ores. It is extremely radioactive. Its most stable isotope, 226Ra, has a half-life of 1602 years and decays into radon (86Rn) gas.

What is inside the nucleus of an atom?
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged. Physicists believe that there is a cluster of Protons and Neutrons within an Atom's nucleus. Friend Premier is quite right. So instead saying inside the nucleus it would be apt to say that nucleus is made up of...
What is the symbol for an atom of radium 88 protons and 140 neutrons?

What has 88 protons and 138 neutrons?
The number of protons of an atom is given by its atomic number. Checking the periodic table, we see that the atom with 88 protons is radium. The isotope of radium with 138 neutrons would thus be 226Ra.
