The groups from 3 to 12 are called transitional metals because the last two shells of the elements included in these groups are incompletely filled. They are also included in d-block.
Groups 3 through 12 are called the transition metals or the d-block.
groups 3-12 are known as transition metals
Group 3-12 elements are called Transition Elements. They are arranged in middle of Periodic Table.

Here we go: C14H20N2SO4 has 14 carbons, 20 hydrogens, 2 nitrogens, 1 sulfur, and 4 oxygens. (That's penicillin, by the way.) The molar mass is the total mass of all the atoms, which works out to be 312g/mol. Now, just get part divided by total for each: Carbon: 12x14=168, 168/312=0.54=54% Hydrogen: 1x20=20, 20/312=0.06=6% Nitrogen: 14x2=28, 28/312=0.09=9% Sulfur: 32x1=32, 32/312=0.1=10% Oxygen: 16x4=64, 64/312=0.21=21% *(just make sure your percents all add up to 100!)
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
The heaviest compound that has been discovered is called Pelosium. It has an atomic mass of 312, with an average half-life of 2 years, and it does not decay.
To find the number of atoms we need to find number of moles of Fe in 312.0 grams. Molar weight of Fe = 56 Number of moles of Fe in 312 grams = 312/56 =5.571 moles. 1 mole of Fe has Avogadro number of atoms. So 5.571 moles of Fe has atoms = 5.571 * Avogadro number. Avogadro number = 6.022 * 10^23 So total atoms = 5.571 * 6.022 * 10^23 = 33.548 * 10^23 * means multiply, ^ means raised to power.

The 10s times table is the easiest one of all! 312 x 10 = 3120 312 x 100 = 31200 312 x 1000 = 312000 312 x 10000 = 3121000

312% of 213= 312% * 213= 3.12 * 213= 664.56
312 12*26 = 312 13*24 = 312
It depends on what version you have, but the one I have has 312 pages.
