I really wish I could help hun but I really don’t know the answers
Answer:
4 electrons .
Explanation:
Carbon must gain four electrons to attain noble gas configuration. Carbon has a total of 6 electrons of which 4 are valence electrons. The four electrons are found in the outermost shell, for a stable configuration Carbon should gain four more electrons to give a 2.8 shell configuration. Most noble gases have 8 electrons in their outer shell with the exception of Helium. By gaining 4 electrons Carbon will have the same shell configuration as Neon.
Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O)
Answer:
Weaker
Explanation:
Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).
