A. Fireworks exploding is the answer
Answer:
b. First determine the mass of the sample and then convert it to the number of atoms using Avogadro's number and the molar mass of the element.
Explanation:
a. First determine the mass of the sample and then convert it to the number of atoms using the molar mass of the element. <em>FALSE. </em>As the mass is in grams and molar mass is in g/mol. This result in the moles of each element, not its number of atoms.
b. First determine the mass of the sample and then convert it to the number of atoms using Avogadro's number and the molar mass of the element. <em>TRUE. </em>Mass and molar mass will result in moles of element. These moles could be converted in number of atoms using Avogadro's number that is in # atoms per mole.
c.Use atomic microscope to determine Avogadro's number, then determine the mass of the sample and convert it to the number of atoms. <em>FALSE. </em>An atomic microscope is not used to determine Avogadro's number.
d.Use atomic microscope to count each atom. <em>FALSE. </em>There is not possible to count every single atom in an element. There are more atoms in a drop of water than stars in the sky.
I hope it helps!
K is larger because atomic size generally increases as you move from top to bottom on a periodic table. and K is lower than Na therefore making it bigger
Answer:
será siempre el mismo número de protones, es decir, siempre será 16. En este caso, los dos primeros números se obtienen siguiendo la configuración 3p4, donde n corresponde al número que se encuentra delante del subnivel s, p, d, f.
