The atom will lose three valence electrons.
<h3>What is meant by valence electron ?</h3>
- A valence electron is an electron that is part of an atom's outer shell in chemistry and physics. If the outer shell is open, the valence electron can take part in the creation of a chemical bond.
- Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
- The chemical properties of an element, such as its valence—whether it can bond with other elements and, if so, how readily and with how many—can be affected by the presence of valence electrons. In this way, the electronic configuration of an element greatly influences its reactivity.
- A valence electron for a main-group element can only be found in the outermost electron shell; for a transition metal, it can also be found in an inner shell.

A significant MOE exists compared to developmental toxicity effect levels.
Blood alcohol levels from ABHS approximate consumption of non-alcoholic beverages.
No significant risk of developmental toxicity is expected from ABHS use.
Ethanol-based topical antiseptic hand rubs, commonly referred to as alcohol-based hand sanitizers (ABHS), are routinely used as the standard of care to reduce the presence of viable bacteria on the skin and are an important element of infection control procedures in the healthcare industry.
There are no reported indications of safety concerns associated with the use of these products in the workplace. However, the prevalence of such alcohol-based products in healthcare facilities and safety questions raised by the U.S. FDA led us to assess the potential for developmental toxicity under relevant product-use scenarios.
Estimates from a physiologically based pharmacokinetic modeling approach suggest that occupational use of alcohol-based topical antiseptics in the healthcare industry can generate low, detectable concentrations of ethanol in blood.
This unintended systemic dose probably reflects contributions from both dermal absorption and inhalation of the volatilized product.

Answer:
Collision theory states that the rate of a chemical reaction is proportional to the number of collisions between reactant molecules. The more often reactant molecules collide, the more often they react with one another, and the faster the reaction rate.
