Answer :
is reduced species.
is oxidized species.
is oxidizing agent.
is reducing agent.
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.
Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.
The balanced redox reaction is :
The half oxidation-reduction reactions are:
Oxidation reaction : 
Reduction reaction : 
From this we conclude that the 
is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and 
is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.
Thus, is reduced species.
is oxidized species.
is oxidizing agent.
is reducing agent.
Making repeated separations of the various substances in the pitchblende, Marie and Pierre used the Curie electrometer to identify the most radioactive fractions. They thus discovered that two fractions, one containing mostly bismuth and the other containing mostly barium, were strongly radioactive.
<h3>What was surprising about pitchblende?</h3>
Since it was no longer appropriate to call them “uranic rays,” Marie proposed a new name: “radioactivity.”
Even more surprising, Marie next found that a uranium ore called pitchblende contained two powerfully radioactive new elements: polonium, which she named for her native Poland, and radium.
<h3>Why is radium more radioactive than uranium?</h3>
It is 2.7 million times more radioactive than the same molar amount of natural uranium (mostly uranium-238), due to its proportionally shorter half-life.

Answer: c.
Electrons are transferred → Ions form → Ions are attracted to each other

Explanation:
Answer:
Explanation:
1: the sciencetific name of a giant squid is called Architeuthis
2: i dont know I think it says diet but: Giant squid mostly eat deep water fishes and other squids.
3: the range of a Giant squid can be found in oceans around the world at depths of at least 2,950 feet, but their exact range is unknown.
4, characteristics,
1: it has two large fins attached to its mantle.
2: the giant squid have many unique features, such as their ability to produce 'ink' to distract and deter predators.
3:
facts,
1: Their eyes are the largest eyes in the animal kingdom and are about 10 inches
2: Their big eyes help them to spy objects in dark depths where most other animals would see nothing
3: Until 2005, nobody had ever seen a giant squid that was alive.
4: According to the stories, an huge squid would wrap its arms around a whale, causing a terrible fight to start.
5: Giant squid have small fins at the rear of their mantles used for locomotion.
Human IMPACT
Not only can squids and octopuses sense sound, but as it turns out, these and other so-called cephalopods might be harmed by growing noise pollution in our oceans—from sources such as offshore drilling, ship motors, sonar use and pile driving.
