Group A1 of the Periodic Table (Hydrogen, Lithium, Sodium . . . ) is an Alkali Metal and only has one valance electron. If the element were to lose that electron, it forms an ion. Each element violently reacts when combined with water.

What is the opposite of Chlorine on the periodic table of elements?
The opposite of Chlorine on the periodic table of elements is Sodium. Chlorine is a halogen located in group 17, while Sodium is an alkali metal located in group 1. They are opposite in terms of their properties and reactivity, with Chlorine being a nonmetal and Sodium being a metal.
How are the elements oxygen and calcium alike and different?
Oxygen and calcium are both elements found on the periodic table. They are different in terms of their chemical properties - oxygen is a nonmetal, while calcium is a metal. Additionally, they have different atomic numbers and atomic masses.
Calcium and Sodium have very nearly the same radii?
No sodium has 11 electrons which means its valence are in the 3s2 orbit while Calcium has 20 electrons its valence electrons are in the 4s2 orbit which is much larger in terms of atomic radii
In terms of periodic law which of these elements are the most similar - sodium phosphorus and sulfur?
They are all in different Group of the Periodic Table, so they are all dissimilar. However, sulphur and phosphorus are in adjacent groups , and in the same period. They are both non-metals. Both produce acidic oxides and acids. Sulphur is in the same Group as oxygen , so has come of oxygen's characteristics e.g. H2O (Water) , H2S(Hydrogen sulphide) Similarly nitrgen and phosphorus , However, they do exhibit variable oxidation states. Sodium is a very reactive metal as do all the other metals in Group '1'. It has only ONE oxidation state. produces basic oxides and hydroxide.
Is potassium fluoride metal or non-metal?
Potassium fluoride is a compound consisting of the metal potassium and the non-metal fluorine. Potassium is a metal found in group 1 of the periodic table, while fluorine is a non-metal found in group 17.
Is group 8 the same as group 0?
Both terms are acceptable due to the fact that eight electrons exist in the outermost shell of all elements in the group. Therefore, one could say that this group has 8 electrons in the outermost shell or that there are no electrons in the outermost shell - as the structure is stable! It is the perspective of a person.
What terms refer to elements in a column of the periodic table?
They are groups
What are terms refer to the periodic table?
Group: a vertical column Period: an horizontal row
How are oxidation numbers predictable using the periodic table?
In very simple terms to achieve the octet atoms either lose valence electrons or gain them. The number of valence electrons for the period 2 elements is relativelly straightforward use the group number and remember to take 10 away from B, C, N, O and F. So as an example boron in group 13 has 3 valence electrons- so gain of +5 or loss of 3. Gaining five seems so excessive so your best guess is +3, which is true in say B2O3As for using the periodic table to predict- not so easy- take gallium - in group 13 has 3 valence electrons- so it could lose 3 to give an octet, which indeed is its most common ON but can also lose 1 electron to form Ga+
In biology which term includes the other four atoms molecules electrons elements and protons?
Molecules Atoms which are elements make up molecules. Protons and electrons make up atoms.
What makes elements similar?
By elements being similar, I assume you mean elements of the same group being similar rather than all elements in general. Elements of the same group are similar in terms of chemical properties because they share a similar electron configuration. For instance group one of the periodic table, the alkali metals, has only one electron in its outermost unfilled orbital. Because chemical reactions are dependent on the exchange and sharing of electrons, the similarity of electron configuration in elements of a group results in them having similar properties. For instance, the alkali metals are all soft and extremely reactive.
How are the terms group and period used on the periodic table?
On the periodic table, a group refers to a column of elements that share similar chemical properties due to having the same number of electrons in their outer shell. A period refers to a row of elements that have the same number of electron shells.
What is the relationship between the periodic table periods and groups in terms of organizing elements based on their properties?
Periods in the periodic table refer to the horizontal rows, while groups refer to the vertical columns. Elements in the same group have similar properties because they have the same number of valence electrons. Elements in the same period have different properties because they have different numbers of electron shells. The periodic table organizes elements based on their properties, with elements in the same group sharing similar characteristics.
How are all of the nonmetal elements on the periodic table related terms of ability to lose electrons?
All non-metals have either 5, 6 or 7 electrons in their octet which makes them suitable to gain electrons to achieve stability. Hence it is difficult for electrons to lose electrons.
How are all of the non metals elements on the periodic table related in terms of ability to loose electrons?
Nonmetals are closer to a full outer shell. They would rather gain electrons to complete the shell. They are unlikely to lose electrons.
In terms of electrons in the periodic table why are group 1 metals very reactive and group 7 non-metals very reactive too?
Group 1 metals are very reactive because they have one electron in their outer shell, which they readily lose to achieve a stable electron configuration. Group 7 non-metals are very reactive because they are one electron short of a full outer shell, so they can easily accept an electron to achieve stability. This makes both group 1 metals and group 7 non-metals highly reactive in order to achieve a stable electron configuration.
Why barium and magnesium have similar chemical properties?
Both of them is an element and they have a symbol that repersent it also, they both have an atomic and mass number. also as they are both in group 2 of the periodic table, they both have two outer shell electrons that react so the sane number give the elements
