In the modern periodic table, the period indicates the value of: (n, l, m, or s)?

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.

Periodic Table Position

Atomic Number: 119
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.

Quick MCQ

The element with atomic number 119 (Uue) would belong to:

A. Group 1

B. Group 2

C. Group 17

D. Group 18

Correct Answer: A. 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।

आवर्त सारणी में स्थिति

Atomic Number: 119
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।

Quick MCQ

परमाणु क्रमांक 119 (Uue) वाला तत्व किस Group में होगा?

A. Group 1

B. Group 2

C. Group 17

D. Group 18

सही उत्तर: A. Group 1
