Writing the Configuration
Starting at the top of the periodic table and moving from left to right across the rows, write the row number, the block letter and how many squares are in each block's section until you get to the desired element. To calculate the electron configuration for phosphorus (P), which is in the third row, p-block, third element in that block, write: 1s2 2s2 2p6 3s2 3p3. Check your work by adding the electron numbers to see if they equal the atomic number of the element; for this example, you would write: 2+2+6+2+3=15, which is the atomic number of phosphorus.
Special Instructions
Because an atom's orbitals sometimes overlap in real life, you must account for that in your configurations. For the d-block, change the row number to one number less than it actually is. For example, the electron configuration for germanium (Ge) is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2. Notice even though you are on row four, it is called "3d" to account for overlap.

Answer:
These systems are defined both by the types of energy and matter they contain and by how that matter and energy move through and between systems. In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed.
Explanation:
Because <span> The half-life of carbon-14 is around 5,700 years. So, by measuring the half-live of the sample, we could predict how old the sample actually is.
</span><span>After 50,000 years there is probably less than 1% of the original C-14 left which make it much more accurate to measure, so, the upward limit is put on 50,000 years.</span>

I think you meant 2.42*10^-6
Remember, the first digit must be between 1 and 10 or - 1 and - 10.
(2.42*10^-6)(1000)
=0.242mm
