Only by measuring the separation between the nuclei of two contacting atoms and halving that distance can one determine the radius of an atom. The illustrations show how the environment around an atom can cause it to have a varied radius, even if it is the same atom.
<h3>How can the atomic size of an element be determined?</h3>
By measuring the distance between the two atoms after two are united, we may determine the atomic size of the new molecule. The third technique for determining an element's atomic size is to create a single covalent link between two atoms and measure the space between them.
Atomic radii in the periodic table change from left to right across a row and from top to bottom along a column. Because of these two patterns, the periodic table's bottom left corner contains the biggest atoms, while the upper right corner has the smallest.

Answer: 8.42 grams of testosterone
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte)
= freezing point constant of benzene= 
m= molality
Weight of solvent (benzene)= 299.0 g = 0.299 kg
Molar mass of solute testosterone= 288.4 g/mol
Mass of solute testosterone added = ?
Thus 8.42 grams of testosterone must be dissolved in 299.0 grams of benzene to reduce the freezing point by 0.500°C.
Answer: The answer is 0.52 grams.
2H2O->2H2+O2
So, we can say that,
2 moles of water= 16 gm of O2
Then
0.065 moles of water=16/2*0.065 gm
=0.52 gm
Hope you understood:)
Explanation:
sodium element with 11 electrons,11protons and 12 neutrons
The formula of Density is known as:
Density = mass/volume
Units: g/cm^3
