What is the charge on an atom after it loses an electron during the formation of a bond?

NARA [144]

Answer:

One positive charge

Explanation:

In a neutral atom, the number of positive and negative particles are equal. This leaves the atom with a net charge of zero, 0.

When the number of protons in an atom is greater than the number of electrons, the atom becomes positively charged. When an atom loses an electron when a bond wants to form, it has a net positive charge.

The number of electrons lost or gained determines the charge.

Which of the following situations indicates an alpha emission?

Angelina_Jolie [31]

Your answer would be C. Alpha decay involves the ejection of 2 protons and 2 neutrons from the nucleus for a total of 4 amu lost. This form of decay is most common in heavy elements.

1. Identify each of the following changes as endothermic, exothermic, or not possible to tell. The matter to keep in perspective

goldenfox [79]

Answer:

When effervescent antacid tablets are dropped into water, the tablets slowly disappear and the water becomes fizzy- endothermic

On a hot day, water vapor condenses out of the air and turns into liquid droplets on the outside of a cold glass of lemonade- exothermic

The copper on the Statue of Liberty oxidizes and turns blue.- endothermic

Explanation:

An exothermic reaction is a reaction in which heat is given out to the surrounding. The temperature of the system increases when an exothermic reaction occurs. An endothermic reaction occurs when heat is absorbed and the temperature of the system decreases. Oxidation of elements and effervescence of antacid solution are endothermic processes.

Given that the water vapour in air losses energy upon condensation to liquid, the process is exothermic

The reaction below virtually goes to completion because cyanide ion forms very stable complexes with Ni2+ ion:[Ni(H2O)6]2+(aq) +

NeX [460]

Answer:

Option A and D are correct.

Unstable species react rapidly.

Stable species do not react rapidly.

Explanation:

The complete question is attached to this solution.

The more stable a reactant is, the less reactive it will be. A stable reactant has a very stable structure in which it will avoid any perturbations. And for a reaction to occur, the bonds in the reactant must break down to form the products. A stable reactant has very strong bonds that aren't easy to break down, hence, reactions involving very stable reactants do not proceed rapidly.

And the more unstable a reactant specie is, the more rapidly it reacts. This is why the reaction involving the less stable isotope of carbon; Carbon-14 is very rapid. It is the same reason as explained above that is responsible for this. The bond between unstable species are not strong and are easily breakable, thereby leading to a quick reaction.

Hope this Helps!!!
