<span>H2. Since the difference in electronegativity between two identical atoms is 0, the resulting molecule is non-polar.</span>
Answer:
Explanation:
The properties that are observed or measured without changing the composition of matter are called physical properties.
color, Temperature, Texture are the physical properties as the composition of matter remains the same.
On the other hand, Radioactivity, Flammability and Reactivity comes under chemical property as during the chemical reactions there might be some changes in the properties.
Answer:
This is simple, if it has a high flammability, and you light it on fire, then that would be a chemical change.

Explanation:
it is a trend on the periodic table. Ionization energy increases from left to right(->) I t also increases down to up
Answer:
Beta decay is most common in elements with a high neutron to proton ratio. Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state.
