Which series of elements have the same number of valence electrons?
Atoms which are present in the same group of the periodic table will have same number of valence electrons. Hence Cl,I of group 17, Na,Ca group 1 and C,Ge group 14 have same valence electrons.
What is the group number and number of valence electrons for lithium?
Valence electrons for representative elements Lithium has a single electron in the second principal energy level, and so we say that lithium has one valence electron.
Which group has the same number of valence electrons?
Within each column, or group, of the table, all the elements have the same number of valence electrons. This explains why all the elements in the same group have very similar chemical properties. For elements in groups 1–2 and 13–18, the number of valence electrons is easy to tell directly from the periodic table.
Do lithium and magnesium have the same number of valence electrons?
Elements in any one group (or column) have the same number of valence electrons; the alkali metals lithium and sodium each have only one valence electron, the alkaline earth metals beryllium and magnesium each have two, and the halogens fluorine and chlorine each have seven valence electrons.
Do elements in the same group have the same valence electrons?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Which two elements have the same number of valence electrons quizlet?
The elements potassium and sodium have similar chemical properties because they have the same number of valence electrons (1).
Which element is in the same group of the periodic table as lithium?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is the group number of lithium?
Group 1

The number of valence electrons
| Periodic table group | Valence Electrons |
|---|---|
| Group 2 (II) (alkaline earth metals) | 2 |
| Groups 3-12 (transition metals) | 2* (The 4s shell is complete and cannot hold any more electrons) |

What group is lithium in?
alkali metals group
Lithium is a soft, silvery-white, metal that heads group 1, the alkali metals group, of the periodic table of the elements. It reacts vigorously with water.
What does group 1 elements have in common?
Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.
Which elements are in the same group?
Which element is chemically similar to lithium quizlet?
The elements sodium and lithium have similar chemical properties because they both have the same…
What do the elements in group 18 have in common?
The members of the group have eight electrons in their outermost orbit (except helium which has two electrons). Thus, they have a stable configuration. Group 18 elements are gases and chemically unreactive, which means they don’t form many compounds. Thus, the elements are known as inert gases.
What group does lithium belong to?
Why is lithium and sodium in the same group?
Lithium, sodium and potassium have same number of valence electron i.e. 1, hence they belong to same group. The group is called alkali metals group because all these elements form oxides which dissolve in water to form alkali.
How many valence electrons does group 4 have?
4 valence electrons
The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
What is the valency of Group 3?
All elements in group 1 have 1 valence electron so they have a valency of +1 as they will tend to give up 1 electron. This is the same for group 2 which will give up two electrons and group 3 which will give up 3 electron .
How many valence electrons does lithium have on the periodic table?
To which group in the periodic table does lithium belong? How many valence electrons does it have? Lithium is an alkali metal (column one) and has one valence electron. The groups of the periodic table are organized in columns (from top to bottom) and some have specific names, while some are part of a larger grouping.
What is the group with the same number of valence electrons?
What is the group of elements with the same number of valence electrons? This is one of the things you can tell from looking at a periodic table. For example, on the leftmost side (group1), each element in that group has 1 valence electron:
Which of the following elements has only one electron present in Valence?
For example- All alkali metals like Sodium ( N a), Potassium ( K), Lithium ( L i), Caesium ( C s), Rubidium ( R b) and Francium ( F r) belong to group 1 ( A) of the periodic table. All these elements have only one electron present in their valence shell.
How many valence electrons are in an alkali metal?
Lithium is an alkali metal (column one) and has one valence electron. The groups of the periodic table are organized in columns (from top to bottom) and some have specific names, while some are part of a larger grouping. For example, group one is the alkali metals and consists of Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
