Answer:
D.atom 2 is not the same , because the mass number is different from atoms 1 and 2
Answer:
Los metaloides o semimetales son un tipo de elementos químicos que muestran un comportamiento intermedio entre los metales y los no metales, en cuanto a asuntos de ionización y propiedades de enlace. ... La lista de los metaloides abarca los siguientes elementos: Boro (B). Silicio (Si).
Explanation:
Answer:
Solar energy causes evaporation; uneven heating of the Earth causes air masses to move; Coriolis forces help storms to take shape; and gravity makes rivers flow downhill. Another relevant factor is the high heat capacity (or specific heat) of water.

During nuclear reactions some mass might be converted into energy and some energy might be converted into mass
Answer:
Explanation:
I₂ + 2 e = 2I⁻
I₂ converts itself into I⁻ by accepting electron . In this process it increases the oxidation number of element from which it takes electron . Hence it is an oxidizing agent .
Similarly O₂ is also an oxidizing agent .
O₂ + 4e = 2O⁻²
Al is a reducing agent .
Al = Al⁺³ + 3 e
Al gives 3 electrons to other element whose oxidation number is reduced . Hence it is reducing agent .
Similarly Cr is also a reducing agent .
Cr = Cr⁺³ + 3 e .
