When an element shares electrons with other atoms of the same or different elements to acquire stable electronic configuration, it is called covalency. If an atom shares 1 electron, its covalency is equal to 1. ... It needs 3 electrons to complete its octet.
Answer:
Stars several times more massive then the sun have a simpler, quicker, and more spectacular evolutionary sequence. Because super giants are so massive, the core temperature gets much hotter than in giants, so supergiants can fuse elements heavier than hydrogen and helium.
Answer:
You have to prepare for the lab (Materials, work, paper etc.)
Set up the lab know where the lab will be taking place
Read thru the experiment before doing the lab
Make a hypothesis
Write down notes, observations, measures anything important to help with the lab!
Answer:
Ionic or electrovalent bonds
Explanation:
Ionic or electrovalent bonds are interatomic or intramolecular bonds which are formed between two kinds of atoms having a large electronegativity difference usually 2.1.
Electronegativity is the property that combines the ability of an atom to gain or lose electrons. It is expressed as the tendency with which atoms of elements attracts valence electrons in a chemical bond.
In this bond type, a metal transfers its electrons to a more electronegative atom which is a non-metal.
