  2. Isotopes of chromium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_chromium

    Naturally occurring chromium (24 Cr) is composed of four stable isotopes; 50 Cr, 52 Cr, 53 Cr, and 54 Cr with 52 Cr being the most abundant (83.789% natural abundance). 50 Cr is suspected of decaying by β + β + to 50 Ti with a half-life of (more than) 1.8×10 17 years.

    Naturally occurring chromium is composed of four stable isotopes; 50 Cr, 52 Cr, 53 Cr and 54 Cr, with 52 Cr being the most abundant (83.789% natural abundance). 50 Cr is observationally stable , as it is theoretically capable of decaying to 50 Ti via double electron capture with a half-life of no less than 1.3 × 10 18 years.

  6. Crossing number inequality - Wikipedia

    en.wikipedia.org/wiki/Crossing_number_inequality

    Thus we can find a graph with at least e − cr(G) edges and n vertices with no crossings, and is thus a planar graph. But from Euler's formula we must then have e − cr(G) ≤ 3n, and the claim follows. (In fact we have e − cr(G) ≤ 3n − 6 for n ≥ 3). To obtain the actual crossing number inequality, we now use a probabilistic argument.
