Chemistry

Tems11 [23]2 years ago
5 0

Answer:

Two electrons fit in the first shell out from the nucleus and eight fit in the second. Every element with more protons than the two of Helium needs to work on shells outside the first one. one you get to ten, you have filled the first two shells.

In a water molecule, oxygen forms one covalent bond with EACH of TWO hydrogen atoms. As a result, the oxygen atom has a stable arrangement of 8 valence electrons. Each hydrogen atom forms only one bond because it needs only two electrons to be stable.

Why do we buy milk by the gallon and a bottle of coke by the liter?
ehidna [41]

Answer:

In 70s we were not much familiar with coca cola. Pepsi were sold in liter and milk is traditionally sold locally sold in gallon.

Explanation:

Sarah Brew said that unlike to the global brand like coca cola, Pepsi are sold at global level but milk is sold at local level follow the local custom measurement. If we look back in history, the milkman sold milk door to door in the form of quartz and the gallons. Same things consumers expected from seller.

These are two ways that play a role in grocery shopping. That's  why the congress make a product list in form of liter and metric and traditional inches , gallons, pounds, milk etc.
