Answer:
Odour is intensive
Explanation:
intensive properties are Independent of the amount of matter
The answer is 2 electrons.
The electron configuration of calcium is 2:8:8:2
Calcium has two electrons in its outermost shell. These are its valence electrons and are the ones used in bonding with other elements. Valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding.
Calcium is a metal. When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms forming ions. The resulting compound is known as an ionic compound.
For example, when calcium metal reacts with chlorine gas, calcium gives up its two valence electrons and Chlorine accepts them resulting in a new substance called calcium chloride in which the two elements have ended up forming ionic bonds.
Answer:
His dad knows about gravity and, unless gravity was not working, anything with mass will be pulled back to earth
Explanation:
:)
The answer is C. A, B, and C would depend on what type of electron it is.
Answer:
Ionic bond is bond between a metal and non metal , metallic bonding happens between positive metals ions and negative electrons in a metal
Explanation:
ionic Bond is the transfer of electrons between a metal and non metal due to strong electrostatic force of attraction between positive metal ions and negative non metal ions
in metallic bonding , there is a force of attraction between positive metal ions and the sea of electrons surrounding it
