How can you predict which elements are reactive under normel conditions and which are unreactive?

The elements with either highest or lowest electronegativities are the most reactive, especially with one another. Elements with mid range electronegativity are less reactive, except for silicon and, especially, carbon, atoms of which can react readily with themselves.

What three things can you predict about an element because of its position on the periodic table?

Whether it is a metal or not or a half metal! How reactive it is! What group it is in! Xx

What can you predict about the properties of xenon and helium?

Helium and Xenon are both Noble(or inert) gases. They are very unreactive. Helium has no known compounds and exists only in its atomic state. Xenon can be forced to react with extremely reactive compounds like Fluorine to form XeF4 . But this reaction is extremely hard, because Xenon is so unreactive. They are both gases with very low boiling temperatures.

What can the reactivity series be used to predict?

It can predict many things e.g. displacement reactions such as copper sulfate + Calcium → Calcium sulfate + Copper as the copper would've been displaced because calcium is more reactive, it also can predict how long it takes for a metal to corrode rust e.g. Gold is used for jewellery because it's shiny and beautiful and it has a very low reactivity. This means that many unreactive metals cost a lot. It can also predict many other things.

How can you predict if an element will form a cation or anion?

You can predict it by its area on the periodic table.

Predict that state of matter and the chemical reactivity of krypton?

Based on the other elements in the same group, like helium and neon, you can predict that it is a gas under normal conditions, and it is not chemically reactive.

What can you predict from an elements place in th periodic table?

its valence electrons, its number of energy levels, how reactive it is, and some properties it has

What can you predict about an element from its position in the periodic?

You can see if its a metalliod or a metal or a non-metal.

What can you predict about an element from its position in the period table?

That whether it is metal or non-metal.

Which scientific method could be used to predict the properties of an element?

Periodic table

How do you predict the properties of an element based on the elements location on the periodic table?


Which do you predict is more commonly found in nature-the element of sodium or sodium bound into compounds such as sodium chloride?

Sodium is highly, highly reactive, so it will always be found in nature combined with some other element. This is true for all alkali and alkali earth metals (the 2 rightmost columns on the periodic table, minus hydrogen).

Chlorine has an atomic number of 17 and argon has an atomic number of 18 what can i predict from this?

chlorine is more chemical reactive than argon.

How do meteorologists predict floods formation?

Hydro-logic condition of the watershed area, current river and stream levels and soil moisture levels is how you can predict floods.

How does the activity series for metals predict if a replacement reaction will occur or not?

A more reactive metal can displace another metal placed down in this series.

How can you predict the products of the reactions based on the activity series of metals?

_Answer">Metals higher in the series will replace metal ions in solution that are lower in the series. AnswerIn general, the more "reactive" (electro-positive) the metallic element, the more stable will be the compounds it forms with other elements. AnswerThe activity series can be used to predict whether or not a reaction will occur -- in other words, a yes-or-no answer. It cannot be used to predict what the products of the reaction are, which is entirely dependent on the specific reactants. See the Related Questions about cupric sulphate and an iron nail for a good description of how to use the activity series to predict if a reaction will happen or not.

Can you predict the location of an element based on its configuration?

Yes, it is possible - the electron configuration is a specific characteristic.

How can you predict the outcome of a chemical reaction?

Your question is difficult to address because so many factors go into making a chemical reaction happen.1) Which elements are more reactive? Generally, a more reactive element will replace a less reactive one in a compound. For example, 2NaBr + Cl2 --> 2NaCl + Br2.2) Are the reactants both dissolving? If so, the relatively-more-positive portion of one compound might bump into, and stick to, the relatively-more-negative portion of the other compound. For example, NaCl and KI both dissolve in water: NaCl + KI --> NaI + KCl3) What will help a reactant gain a stable configuration? For example, oxygen is stable when it has 8 electrons in its valence shell; hydrogen is stable when it has two. Oxygen normally has 6, hydrogen normally has 1. If two hydrogens share that one electron with oxygen and share one of oxygen's in return, then the valence shells are complete and the produce has a stable configuration: O2 + 2H2 --> 2H2O.So in order to find out the answer to your question, you might want to look into some of the more specific questions that make it up, like: how do you predict the electron configuration of an element? How do you tell how reactive an element is? How do you predict how stable a compound is?

Why is the arrangement of electrons in an element the key to understanding why each element behaves the way it does?

The reactivity of an element is determined by its valence electrons. Understanding how they are arranged in their orbital clouds helps predict how the elements will react.

Explain how to use the activity series to predict chemical behavior?

In single-displacement, if the activity of the free element is greater than the element in the compound, the reaction will happen.
