Polonium and radium's affect on our lives today are for example the meters on our How_does_polonium_and_radium_affect_your_lives_today, they glow because of the radium and also some wristwatches the light you get when you press the button on the side. Radium was discovered by a woman named Marie Curie, she's married, but she obviously died because of too much radium.

Bequerel was the first to note radioactivity, in 1896. Curie discovered radium in 1898, after experiments with uranium and then pitchblende.
The neutrons aren't really relevant, since we don't know what the mass of the radium nucleus was and the element is determined strictly by the number of protons anyway. Radium has an atomic number of 88; losing 4 protons would make the atomic number 84, which is polonium. (This is probably really a two-step process: radium -> radon -> polonium, where each step is an alpha decay.)
how did band aids eaiser
a stair is an inclined plane because it can make it eaiser for you to walk on it to get where you need inclined planes and other simple machines or even compound machines make our life eaiser
it makes our lives eaiser by making it easy to get from place to place
Polonium is a chemical element. It does not make a sound.
Marie Curie discovered radium and polonium and made huge inroads in the research of radioactivity and it's benefits. As a note of interest, both her and her husband Pierre's journals are still radioactive.
Polonium is an element. So the only element that makes up polonium is itself.
The polonium hydride PoH2 is known.
to make things eaiser tp keep together
Her husband, Pierre Curie, worked with Marie Curie when they discovered Polonium. The Curies also discovered that Thorium, discovered in 1829 by Jöns Jakob Berzelius, emits radiation.
