Answer: remove a H2 molecule from the left side of the equation
Explanation:
Answer:
The statement is considered to be true
Explanation:
The statement is true because when elements chemically combine, there are interactions between their valence electrons, causing the two elements to be bonded together to form what is known as a compound.
Compounds can only be formed from interactions between two or more elements. examples include:
Hydrogen + Oxygen = H2O (water)
Sodium + Chlorine = NaCl
Note that if atoms of the same element combine, what is formed is a molecule, not a compound. Some atoms usually do this to attain stability. examples include = O2 H2 and N2. They are oxygen molecule, hydrogen molecule, and nitrogen molecule respectively.
Compounds are only formed when different elements combine to attain electronic stability.
1. Atomic weight of fluorine
2. Number of proton and neutrons found in the nucleus of the element
3. And every number uniquely identifies each of the the elements
Depends on what the problems are, you are going to have to be a bit more specific, Young Padawan
