One Angstrom is defined as 10-10 centimeters. Therefore, the number of any units with a diameter of 2.2 Angstroms that would be required to span 1.0 cm is 1.0/10 -10 or 4.5 X 109 calcium atoms., to the justifiable number of significant digits.

How many chromium atoms would have to be lined up to span 1.0 mm if chromium is about 1.9 Å?
An angstrom = 1 X 10^-10 meters 1.0 mm = 0.001 meters so, 1.9 * 1 X 10^-10 = 1.9 X 10^-10 meter per chromium so 0.001 meters ( 1 meter/1.9 X 10^-10) = 5263158 atoms of chromium ------------------------------------------ ( 5.3 X 10^6 atoms )
Is chromium nitrate ionic or molecular?
both. the chromium metal would form an ionic bond, and chromium nitrate is molecular because it contains atoms of different elements.
How many krypton atoms would have to be lined up to span 3.5mm?
The radius of krypton is 110 picometers, which is 220 picometers diameter, or the length we want of the Kr atom. So, convert 3.5 millimeters (10^9/10^3) = 3500000 picometers/220 picometers = 15,909 atoms of Krypton
How many gold atoms would have to be lined up to span 4.0 mm?
The radius of gold is 144 picometers, so....,144 picometers (103/1012)= 1.44 X 10 -7 mm------------------------so,4.0 mm/1.44 X 10 -7 mm= 2.8 X 107 * 2 ( because you need to double radius to get diameter end to end )= 5.6 X 107 gold atoms lined up======================
What is the name of the compound CrS?
Chromium (ii) sulfide is CrS. The ii indicates that chromium can take on different valence characteristics, here sharing two electrons with the sulphur atom. The same elements can also make a different mineral compound, Cr2S3 where Chromium atoms share 3 electrons instead of two.

How many copper atoms would you have to line up side by side to form a line a meter long?
1,000,000,000 atoms lined up side by side will equal 1 meter * * * * * I disagree. The diameter of a copper atom is approx 250 picometres = 2.5*10-10 metres. You would therefore require 4 billion atoms.

Can atoms grow and shrink?
The diameter is lower now.

It is estimated 50 million atoms lined up toghether would only occupy about how much room?
About half of a centimeter, more or less depending on what elements the atoms were.
How long would a line formed by 10000000 copper atoms be?
100,000,000 copper atoms4 or 5 billionAccording to the link, the diameter of a copper atom is 2.28e-10 m, or 2.28x10-10m. The answer to your question is 1/(2.28x10-10). this can be rewritten as follows:(1/2.28)(1/10-10) = (approx. 0.439)(1010) = 4.39x109.You could say "over 4 billion".
How many oxygen atoms lined up in a row in one nanometer space?
Depends on the the atom size. A hydrogen atom is 0.12 nanometer in diameter, which would make the answer 1/0.12= 8.33. A cesium atom is 0.34 nanometer, which would make the answer 1/0.34= 2.94. The answer is thus dependent on the element.
How many gold atoms would have to be lined up to span 1.5 mm?
The atomic radii of an Au atom is 174 pm. A pico meter is 10^-12 of a meter. Use this to easily convert to mm. Then multiply this value by two to find the diameter of one Au atom in mm. Finally, divide 1.5 by this answer to find the total Au atoms to span. You should get approximately 4.45 x 10^7 Au atoms.
