True, because his model has the electrons in the sphere of the atom, Thomson’s model was called the “Plum Pudding” model because it was popular and relatable at his time.
Hope this helps!! ^v^
Answer:
D
Explanation:
Because the other answers can not to be considered to be chemical properties.
Chemical means that the after the reaction the checal properties have changed in a way that it can no longer be called the same ad befor. In short, it can not be undone.
Burning a match is irriversable, meaning you can never go back to the previous situation because the chemical compounds have changed (dramatically).
Melted ice can be frozen again. Steam (evaporated water) can condensate to water which can be heated and can boil again. The chemical contents remain H2O.
The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.
Another compound that can be used to treat acidic soil is calcium carbonate.<span />
