What are the most frequently occurring chemical elements in living things?
carbon, hydrogen, oxygen, and nitrogen.
What are the most abundant elements found in cells?
the most abundant chemical in cells is water.
Which type of element donates the electron?
Fluorine is the element that would most likely to gain electrons in a chemical bond Metals ususally give electrons, and nonmentals usually gain electrons.
What factors determine the phase of a substance at a given temperature?
It's chemical properties. Each element has a specific boiling point and melting point, as well as freezing point. At room temperature, some elements (water being the most obvious) are liquid at room temperatures. However, some elements are solids (Sodium Chloride, NaCl) or gases (oxygen O2) at room temperature. This all soley depends on the elements specific chemical properties.
What are the verticle colums in the periodic table called?
The vertical columns are called groups; at one time it was common to use Roman numerals to describe the groups of elements, but now the preferred usage is standard numbers.The groups also have names, in some cases for individual groups and in other cases for a block of groups.Group 1 is called the Alkali Metals, the most active metalsGroup 2 is called the Alkaline Earth MetalsGroups 3-12 are called the Transition Metals, and include some of our most useful metallic elements.Groups 13-16 are the PMN Elements (Post-Transition Metals, Metalloids and Non-metals - metals are near the bottom, non-metals are near the top - a complex block)Group 17 is the Halogens, the most active non-metalsGroup 18 is the Noble Gases, the least active non-metalsThe two rows of elements usually displayed at the very bottom of a periodic table are called the Lanthanides and Actinides, and they fit into the periodic table between Group2 and Group 3. So we might call the Lanthanides and Actinides Group 2.5
In which two groups are the elements most similar in their chemical properties?
1 and 2
How do you find the most similar elements in the periodic table?
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
How did Mendeleev list the elements?
The most important principle was the listing in groups, after similar chemical or physical properties.
Most chemical reactions can be divided into five main groups?
True, the five groups are combustion, synthesis, decompostion, single displacement, and double discplacement.
Do elements in a group have different charges?
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.
Where can a person find the Periodic Table of Elements?
The Periodic Table of Elements can be found in most introductory chemistry and science books. It can also be found on a variety of online sources. It arranges the chemical elements by different groups.
Which of the groups of elements are the most reactive?
groups 11 and 12
Why are elements grouped in the periodic table?
I am assuming you mean to ask why elements go into specific groups Elements that have the same number of valence electrons are put into the same group. Because they all have the same number of valence electrons, it could also be said that elements are put into groups based on their chemical properties.
What are most of the elements called on the periodic table?
They are all chemical elements.
Which best describes the elements that comprise most of earth's crust?
a chemical combination of a few elements. n.c101
What role of properties of elements and simple molecules play in chemical evolution?
The most important is the electronegativity of chemical elements.
Why are elements in groups 1 and 7 mostly used in the form of compounds?
In chemical education it is the most siplest start for explaining reaction equations: they react 1 to 1.
