Answer: C.
ability of an atom to attract an electron from another atom toward itself.
Explanation:
Electronegativity is the chemical property that describes the ability of an atom to attract electron to itself. It is responsible for bond formation between atoms.
Answer:
Ionization energy
Electronegativity
Explanation:
-due to its smaller ionic radius....the electron in the outter most shell tends to expierence a stronger nuclear attraction...which makes it harder to remove the electron from the sodium atom
-Rubidium has lesser ionization energy because its (i) affected by its larger ionic radius which tends to lessen the nuclear attraction ...hence making it easier to remove the electron...(ii)and also by the screening effect done by the inner shells, which also tends to lessen the nuclear attraction.
Sodium has a higher electronegativity than rubidium;
Electronegativity is the charge density of electrons in an atom...in which its high when the atomic radius is smaller...
So hence due to the sodium atomic radius being smaller...it tends to have a higher charge density than rubidium....which then gives it a higher electronegativity value
The molar mass of NH3
N = 14
H3 = 3
total = 17
The fraction of nitrogen is 14/17
So 14/17 x 125 = 102.94g
Pure water does
not have enough ions to conduct electricity. A mixture of metals such as iron,
zinc and copper in the wet soil can trigger electrolysis that requires excess
energy in the form of over potential to conduct electricity. The excess energy
is needed due to limited self-ionization of water. The wet soil then can
conduct current when positive and negative ions are present. The water ions begin
to flow from anode (positive electrode) to cathode (negative electrode) to be oxidize
and produce electricity.
