How much heat is absorbed as 7.56 g of ice is heated from −30.0°c to its normal melting point?

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

so what is the problem with your lab report and whats the subject of the lab report? i will you

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
