What elements have the same properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
Where can you find similar properties?
The periodic trend states that elements in the same group (column) in the periodic table have similar properties.
Do N and P have similar properties?
Nitrogen and phosphorous are part of the same ‘family’ on the periodic table, group 15, also called the nitrogen group. Since phosphorus is just below nitrogen, we can expect nitrogen and phosphorus to have some similar properties. They are nonmetals and have similar properties when making compounds.
What two elements are most similar?
Which two elements have the most similar chemical properties?
- Finding what elements have the most similar chemical properties is easy.
- Let’s try an example.

- Answer: The correct answer 1: beryllium and magnesium.
What group has two valence electrons?
Calcium
What element has 2 valence electrons and is shiny?
ALKALINE EARTH METALS
How many valence electrons does group 13 have?
The number of valence electrons
| Periodic table group | Valence Electrons |
|---|---|
| Groups 3-12 (transition metals) | 2* (The 4s shell is complete and cannot hold any more electrons) |
| Group 13 (III) (boron group) | 3 |
| Group 14 (IV) (carbon group) | 4 |
| Group 15 (V) (pnictogens) | 5 |
Which group of elements has 8 valence electrons?
Noble Gases
What does it mean if an element has 8 valence electrons?
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.
Which group of elements has 7 valence electrons?
Halogens
How many valence electrons does an atom of oxygen have?
six valence electrons
Why does oxygen have 2 valence electrons?
1 Answer. Stefan V. Oxygen needs 2 more electrons to fill its outermost shell. As you can see, oxygen has 2 of its 8 electrons in the shell closest to the nucleus, and the remaining 6 electrons – which are called valence electrons – in its second shell – this is oxygen’s outermost shell.
Is oxygen a cation or anion?
Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).
How many valence electrons does s 32 have?
6 valence electrons
Can you have 9 valence electrons?
Some molecules can accommodate more than 8 valence electrons because they have expanded valence shells. These molecules are from periods 3 or higher because starting from n=3, atoms have d-orbitals that can accommodate for more that 9 valence electrons.
Why does sulfur only have 6 valence electrons?
Sulfur has one more electron pair in its 3s subshell so it can undergo excitation one more time and place the electron in another empty 3d orbital. Now sulfur has 6 unpaired electrons which means it can form 6 covalent bonds to give a total of 12 electrons around its valence shell.
How many valence electrons are in lithium?
one valence electron
Why does lithium only have 1 valence electrons?
Atoms having four outermost electrons possess both positive and negative valency and atoms having eight outermost electrons have zero valencies (i.e. noble gases). Alkali metals like lithium reached the stable (nearest inert gas configuration) by losing one outermost electron. So that the valency of lithium (Li) is 1.
Why is lithium Valency 1?
Valency of Lithium – Atomic number of lithium is 3. Its electronic configuration is 2,1. So, it needs to lose one electron to attain stability and get electronic configuration like noble gas Helium. Thus, its valency is 1.
Does lithium have a full valence shell?
A full valence shell is the most stable electron configuration. In comparison, the group 1 elements, including hydrogen (H), lithium (Li), and sodium (Na), all have one electron in their outermost shells. This means that they can achieve a stable configuration and a filled outer shell by donating or losing an electron.
Does lithium lose or gain valence electrons?
Lithium, an alkali metal with three electrons, is also an exception to the octet rule. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons. There are two ways in which atoms can satisfy the octet rule.
Is lithium cation or anion?
Lithium(1+) is a monovalent inorganic cation, a monoatomic monocation and an alkali metal cation….4.3Related Element.

What element has properties like Lithium?
Metal
Does beryllium have similar properties to Lithium?
Lithium and beryllium are the first elements of Group 1 and 2 respectively exhibit some properties which are different from those of the other members of the respective group. They both show similarity in properties of the second element of the following group.
Does hydrogen have similar properties to Lithium?
Hydrogen is not an alkali metal itself, but has some similar properties due to its simple one proton (loctated in the nucleus), one electron arrangement. For lithium, there are two 1 s electrons in an inner orbit and one 2 s electron in the outer orbit. The same pattern holds for sodium and potassium.
How is beryllium similar to lithium?
Both of them have small size and thus they have better ionizing energy and also they both form a stable hydride than any other alkali metal. Both of these metals show anomalous behaviour due to their high electronegativity and high polarizing power. 2. Can Lithium React with Oxygen?
