Atomic radius- a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
Electron Affinity-the electron affinityof an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
Electronegativity-a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
Lonization energy- qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
Answer: 0.011 moles.
Explanation:-
To calculate the moles, we use the equation:
Given :
Mass of copper = 0.71 g
Molar mass of copper = 63.5 g/mol
Putting i the values, we get:
Thus the number of moles of copper in 0.71 g of copper is 0.011 moles.
Well, one mole would be considered as 6.02 x 1023 (atoms). Which in the copper form, this would be considered to be as 63.66 grams of copper. Know, by knowing this information, we're now able to figured out the question.
53.3 ÷ (atoms) 6.02 x 1023 ...
Which as a result, we then have 2665 over.
