Answer: A. The water molecules electrostatically interact with the ions in the crystal and let the ions move freely.
Explanation: Took the test. :D
Answer:
False
Explanation:
Heres what its made of:
The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.
The electron configuration for a neutral atom of oxygen would be the final option:
O : 1s^2 2s^2 2p^4.
Knowing that this is a neutral atom of oxygen, and that it posses the same number of electrons and protons, the total number of electrons would be 8. Which can be found out by adding the exponents for each subshell.
The three broad classes of elements are:
Metals
Metalloids
Nonmetals
Answer:
One may conclude that they have an identical number of electrons in their outermost shell, therefore the can be substituted for one another.
Explanation:
Elements in the same family tend to behave similarly in chemical reactions because they have similar number of valence electrons in their outermost shell and they also have similar chemical properties.
Valence electrons are responsible for reactions between elements. The valence electron makes it possible for atoms to combine and react, therefore, elements in a family behave similarly in chemical reactions because they have an identical number of electrons in their outermost shell.
