Answer:
1 electron
Explanation:
Fluorine is a nonmetal with a high electronegativity and electron affinity so it tends to gain electrons to reach stability. According to the octet rule, fluorine will gain enough electrons so as to complete its valence shell with 8 electrons. Fluorine is in the Group 17 in the Periodic Table, which means it has 7 electrons in its valence shell. Therefore, it will gain 1 electron to complete its octet and form the anion F⁻.
Some examples of physical properties are:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils.
melting point (intensive): the temperature at which a substance melts.
Answer:
The correct answer is the a=heat
Explanation:
Hello! Let's solve this!
Heat is responsible for regulating the temperature on Earth. When the temperature rises, the evaporation of water occurs, so it influences the water cycle. It also influences the climatic phenomena by increasing and lowering the temperature.
The correct answer is the a=heat
It is based on the law of conservation of energy , which says that energy is neither created nor destroyed during a chemical reaction . I’m calorimeter , this means that the heat gained by the water in calorimeter must have been released by the sample or reaction taking place in the calorimeter .
