What else can I help you with?
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
Does a group of elements share the same number of valence electrons?
Yes In Groups 1A through 8A
What is the number of valence electron for all the elements in periodic table group 1A 1?
Group 1A (1) elements in the periodic table all have 1 valence electron. This includes elements like hydrogen, lithium, sodium, and potassium.
How many valence electrons does a group 1A metal atom have?
they all have one valence electron.
How many electrons do group 1A elements have in their valence shell?
Group 1A elements, also known as alkali metals, have one electron in their valence shell. This single valence electron is responsible for their high reactivity and tendency to lose that electron to form positive ions. As you move down the group, the number of electron shells increases, but the number of valence electrons remains the same at one.

What element is in group 1a and higher atomic number than chlorine but lower number than bromine?
The element in Group 1A with a higher atomic number than chlorine but lower than bromine is iodine.
What do elements in the same group or family share?
Elements in the same family are related because of shared properties. For example, all the elements in the noble gas family do not react to anything and are colorless, nonflammable, odorless, and tasteless under normal circumstances.
What is the name of the family that is group A?
group 1A on the periodic table? that should be the alkali metals. i just learned that in class. lol.
What are the elements in groups 1A to 8A called?
The elements in groups 1A to 8A are called the representative elements or main group elements. Each group corresponds to a specific column on the periodic table and has similar chemical properties due to their electron configurations.
What is the number of valence electrons in family 1A of the periodic table?
One valence electron.
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
What are the family names for groups 1a 2a 3a 4a 5a 6a 7a 8a?
The family names for the groups in the periodic table are as follows: Group 1A is the Alkali Metals, Group 2A is the Alkaline Earth Metals, Group 3A is the Boron Group, Group 4A is the Carbon Group, Group 5A is the Nitrogen Group, Group 6A is the Chalcogens, Group 7A is the Halogens, and Group 8A is the Noble Gases. These groups represent a range of elemental properties and reactivities.
Does a group of elements share the same number of valence electrons?
Yes In Groups 1A through 8A
How many valence electrons are in the sodium family?
Elements in the sodium family (Group 1A or Group 1) have 1 valence electron. This is because they have one electron in their outermost energy level.
What are the elements in the group 1A on the periodic table?
There are 7 elements in group 1: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. All of these (except hydrogen) are considered alkali metals. They react very easily with other elements.
Which element of the group 1A has the largest atom?
Francium (Fr) has the largest atom among the group 1A elements. It has the highest atomic number and electron shells, resulting in a larger atomic size compared to other group 1A elements such as lithium, sodium, and potassium.
