The element with atomic number 119 (Uue) would belong to which group?
परमाणु क्रमांक 119 (Uue) वाला तत्व किस समूह से संबंधित होगा?
+
Answer
Group 1 — Alkali Metals
Explanation
The element with atomic number 119 is expected to have the
electronic configuration:
[Og] 8s1
Since its outermost configuration is ns1, it will belong to Group 1 of the modern periodic table.
Group 1 elements are known as alkali metals.
[Og] 8s1
Since its outermost configuration is ns1, it will belong to Group 1 of the modern periodic table.
Group 1 elements are known as alkali metals.
Periodic Table Position
Atomic Number: 119
Expected Symbol: Uue
Period: 8
Group: 1
Block: s-block
Expected Category: Alkali metal
Outer Configuration: 8s1
Expected Symbol: Uue
Period: 8
Group: 1
Block: s-block
Expected Category: Alkali metal
Outer Configuration: 8s1
Why Group 1?
Elements of Group 1 generally have one electron in their outermost
s-orbital:
General configuration = ns1
For element 119:
[Og] 8s1
Therefore, it is expected to be placed in Group 1.
General configuration = ns1
For element 119:
[Og] 8s1
Therefore, it is expected to be placed in Group 1.

उत्तर
Group 1 — Alkali Metals
व्याख्या
परमाणु क्रमांक 119 वाले तत्व का अपेक्षित electronic
configuration होगा:
[Og] 8s1
इसकी बाहरी configuration ns1 है, इसलिए यह आधुनिक आवर्त सारणी के Group 1 में रखा जाएगा।
Group 1 के तत्वों को Alkali Metals कहा जाता है।
[Og] 8s1
इसकी बाहरी configuration ns1 है, इसलिए यह आधुनिक आवर्त सारणी के Group 1 में रखा जाएगा।
Group 1 के तत्वों को Alkali Metals कहा जाता है।
आवर्त सारणी में स्थिति
Atomic Number: 119
Expected Symbol: Uue
Period: 8
Group: 1
Block: s-block
Expected Category: Alkali metal
Outer Configuration: 8s1
Expected Symbol: Uue
Period: 8
Group: 1
Block: s-block
Expected Category: Alkali metal
Outer Configuration: 8s1
Group 1 क्यों?
Group 1 के तत्वों की outermost shell में सामान्यतः एक electron
होता है:
General configuration = ns1
Element 119 की expected configuration:
[Og] 8s1
इसलिए यह Group 1 का तत्व होगा।
General configuration = ns1
Element 119 की expected configuration:
[Og] 8s1
इसलिए यह Group 1 का तत्व होगा।
