"Estimate the average mass density of asodium atom assuming its size to be about 2.5.(Use the known values of Avogadro's number and sodium's atomic mass.). Compare it with the density of sodium in its crystallinephase: 970 kg $m^{-<!--\; -\; -->3}$. Are the two densities of the sameorder of magnitude? If so, why?"

Atomic number refers to the number of present in an atom.
neutrons
electrons
protons

The half-life for radioactive decay of 14C is 5730 years. An archaeological artifact containing wood had only 80% of the 14C found in a living tree. Calculate the sample's age.

The half-life for the radioactive decay of C-14 is 5730 years.How long will it take for 30% of the C-14 atoms in a sample of C-14 to decay?

What is the mass number of an atom which contains 28 protons, 28 electrons, and 34 neutrons?
A) 28
B) 56

How does the sun burn in space as the sun is a ball of fire?

Potassium exits in mainly two isotopic form,39k and 41k and their abundance in nature are 93% and 7%. What is the average atomic mass of potassium.

The positively charged atom is known as a _______

Gram Atomic mass is just the atomic mass expressed in grams ...ie, atomic mass with gram as units. One more information about it gram atomic mass and gram atom are the same thing. Later a formula is given that: Gram atom = mass in grams / Atomic mass [RAM]. There are questions also that use this formula in which we have to find the number of "gram atoms " in a given mass of substance. So what is the real meaning of gram atom and the formula?

What are the advantages of nuclear energy?

A Atom has a nucleus which is surrounded by electrons and protons. A cell in a leaf also has a nucleus, so the nucleus in the leaf also has electrons and protons surrounding it?
