The octet rules says that an atom can only have a maximum of 8 electrons in its valence shell. This applies from non-metals to metalloids to metals. In this case, sulfur can have <span>more than 8 electrons in its valence when it acquires a larger state specifically in an ionic state. For example SO4 2- where the 2- adds to the number of valence electrons</span>
Answer:
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state. ...
Explanation:
Therefore, spectroscopy can be used to identify elements in matter of unknown composition.
Answer: drinking, bathing.
Explanation:
Answer:
The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. The diameter of an atom is on the order of 10−10 m, whereas the diameter of the nucleus is roughly 10−15 m—about 100,000 times smaller.
