First group elememts are called alkali metal because they are highle reactive metal and they produce hydrogen gas as a result of any reaction.
they have only one valence electron that is why they can react vigorously with any metal and they are called alkali because they form easily soluble base.
What else can I help you with?
What are families of elements with similar chemical properties called?
Families of elements with similar chemical properties are called "groups" or "families" on the periodic table. Elements within the same group typically have the same number of valence electrons, which gives them similar reactivity and chemical properties.
Which choice represents a group of elements with common characteristics?
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
How are the elements aranged in a periodic table?
They are arranged in ascending order by proton number. There are eight vertical groups. Elements in each group share similar properties and have the same number of valence electrons. Group I elements have one valence electron, and Group V elements have five valence electrons. Group 0 (the eighth group) elements have either two or eight valence electrons. The elements are also arranged horizontally in Periods. Hydrogen and helium are in Period 1; lithium, neon and the elements between them are in Period 2; and sodium, argon and the elements between them are in Period 3. So on. The Period an element is in indicates the number of electron shells the atom has. Hydrogen has one shell, sodium has three. Metals are found on the left side of the periodic table. Non-metals are found on the right side. Elements between Group II and Group III are called transition metals. For example, iron, gold, copper, nickel and silver are all transition metals. Some elements found between metals and non-metals are metalloids, which have properties similar to both metals and non-metals.
What elements have 5 electrons in their electron dot diagrams?
The elements that have 5 electrons in the dot diagram means that they have 5 valence electrons. These elements are found in group 5A. Elements include, nitrogen, phosphorus, arsenic, antimony, and bismuth.
Why do the elements belonging to a particular group exhibit similar chemical behavior?
Elements in the same group have the same number of valence electrons, which dictates their chemical behavior. Valence electrons are responsible for the way atoms interact with each other in chemical reactions. This similarity in valence electron configuration leads to similar chemical reactivity among group members.
What are elements in the first group of period table called?
alkali metals
What elements are in group 17?
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
What are the elements in group 17?
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in the first group with one outer shell electron and high reactivity are called alkali metals. This group includes elements such as lithium, sodium, and potassium. Alkali metals readily lose their outer electron to form positive ions in chemical reactions.
The representative elements are usually called?
The representative elements are usually called the main group elements or the Group A elements. They are located in the leftmost and middle sections of the periodic table, excluding the transition metals.
Why are group 3 called boron family?
Group 3 elements are called the boron family because the first element in this group is boron. The group is also known as the "triad" group since it consists of three elements - boron, aluminum, and gallium. These elements share similar chemical properties and form cations with a 3+ charge.
What is a group of elements on a periodic table called?
It is called an elemental group.
Elements of Group 1 Are Called what?
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
What is the mane of the elements in group 17?
The elements in group 17 are collectively called the halogens.
Why are the elements in vertical group on the periodic table called families?
The elements in vertical group are called families because the elements possess same characteristics.
Elements in the first group?
The first group of the periodic table consists of alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium. These elements have one electron in their outer shell and are highly reactive. They are soft and silvery in appearance.
Elements in a column are called a?
Vertical columns are called groups. Horizontal rows are called periods.
