Electron affinity: The enthalpy change that results from adding an electron to a gaseous atom.

Electron affinity is becoming less negative (less exothermic) and less likely to gain an electron.

Tropical Grassland or Savanna 

These are hot, tropical areas, averaging 24–29ºC with a low or seasonal rainfall of between 70 and 130 cm per year.

As with grasslands, the predominant mammals are the grazers. 

 In Africa, the large herds of grazing animals provide food for many different kinds of large carnivores (lions, hyenas, leopards). 

The world’s greatest assemblages of large mammals occur in the savanna biome.
