Density = Mass / Volume
Input the values in their respective places and then use algebra to solve for volume.
Hope that helps.
Answer:
7 Valence Electrons.
Explanation:
The Valence electrons are referred to as the number of electrons in the outermost shell of an atom.
When given the electronic configuration, the valence can be calculated by adding the superscript of the hugest number coefficient.
The highest number coefficient in this electronc cnfiguration is 2. The sum of it's superscript is 2 (in 2s²) and 5 ( in 2p⁵). That is 2 + 5 = 7
How to test the answer?
The atom given has 9 electrons ( 2 + 2 + 5).
The K shell is being occupied by 2 electrons, the next shell; M shell which can occupy maximum of 8 electrons is being occupied by 7 electrons ( 9 - 7). And in this atom, the M shell is the outermost shell.
Answer:
Ionic bonding is the complete transfer of valence electron
Explanation:
In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD
