What is the simple definition of reactivity?
noun. the quality or condition of being reactive. Chemistry. the relative capacity of an atom, molecule, or radical to undergo a chemical reaction with another atom, molecule, or compound.
What is the definition of reactivity in chemistry?
Reactive chemicals are defined as those substances which can, in contact with air, water or other common substances, vigorously or violently give off heat, energy or toxic gases or vapors.
What are examples of reactivity?
Reactivity is the ability of matter to combine chemically with other substances. For example, iron is highly reactive with oxygen. When it combines with oxygen, it forms the reddish powder called rust (see Figure below). Rust is not iron but an entirely different substance that consists of both iron and oxygen.
What determines reactivity definition?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.
What is another word for reactivity?

What is reactivity in sociology?
reactivity. the extent to which humans being studied respond to the research process or the researcher by changing their behavior intentionally or unintentionally. ethical issues. when people are being studied they must be treated ethically. Early Sociologists who shaped the discipline.
What is a reactive person?
To be reactive is to be ready to react or respond to something else — as opposed to ready to act on one’s own. A person who’s reactive does things only in response to others. But if you’re a reactive person, then you only react; you’re always ready to react but not to act on your own.
What is the opposite of reactivity?
proactive Add to list Share. Active means “doing something.” The prefix pro- means “before.” So if you are proactive, you are ready before something happens. The opposite is being reactive, or waiting for things to unfold before responding.
What is reactivity bias?
A type of experimental error where participants in an experiment change their normal behaviour as a direct result of the experimental conditions.
What is reactivity observation?
Reactivity, also known as the observer effect, takes place when the act of doing the research changes the behavior of participants, thereby making the findings of the research subject to error. Different types of reactivity have been identified.
How does a reactive person act?
reactive Add to list Share. To be reactive is to be ready to react or respond to something else — as opposed to ready to act on one’s own. A person who’s reactive does things only in response to others. But if you’re a reactive person, then you only react; you’re always ready to react but not to act on your own.
What are the examples of reactivity?
Photosynthesis. Plants apply a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen.
What does it mean for a substance to have a high reactivity?
When we say that a substance has high reactivity then it means the substance is able to react readily with another substance. For example, atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. Since, it has only one valence electron and to attain stability it just needs 8 electrons in its valence shell.
Which element shows the least reactivity?
The least reactive elements are the noble gases . Within this group, helium is the least reactive element, forming no stable compounds. Metal can have multiple oxidation states and tend to have intermediate reactivity. Metals with low reactivity are called noble metals.
Which element has more reactivity?
The most reactive element is fluorine , the first element in the halogen group. The most reactive metal is francium , the last alkali metal (and most expensive element). However, francium is an unstable radioactive element, only found in trace amounts.
