No, they are not.

Bromine 81 has 35 electrons, which is the same number of electrons as a neutral bromine atom since it is the most common isotope of bromine.
No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
Bromine-35 refers to an isotope of bromine that has an atomic mass of 35 atomic mass units. It is one of the stable isotopes of bromine, with approximately 75% natural abundance. Isotopes of an element have the same number of protons but differing numbers of neutrons in their atomic nuclei.
No, the diffusion rate of oxygen and bromine is not the same. Oxygen, being a smaller and lighter molecule, diffuses faster than bromine, which is larger and heavier. This is based on Graham's law of diffusion, which states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
A mango contains neither papain nor bromelain. Papain is an enzyme found in papaya, while bromelain is an enzyme found in pineapples. Mangos contain enzymes such as amylases and proteases, but not papain or bromelain.
the stem of the pineapple contains an enzyme called bromelain.
Ananas comosus.
Br (Bromine) is a period 4 element in the same group as F.
The word bromelain refers to a type of enzyme. This enzyme is obtained from pineapples. The word bromelain is derived from the word bromeliad, the Latin word for the pineapple genus.
no the do not bromine has 4 and oxygen has 2
Bromelain is extracted from the pineapple stem, the main fruit contains very little bromelain. Also Bromelain is heat labile (destroyed by heat). As the canning process involves heating the canned produce at very high temperatures for a few seconds the small amount of bromelain that may be present would be destroyed.
Bromine vapor is chemically the same as bromine its just physically different so the symbol is still Br. :-)
Common names for bromelain include pineapple enzyme, pineapple extract, and Ananase.
bromine............
It's BROMINE. That is the element that is a liquid in the same period as Fe.
Bromine is in the third period and belongs in the same family (Group 17) as iodine.
