Question

расположите элементы по порядку возрастания металлических свойств 1)бор.2)берилий.3)углерод.4)литий

Answer 1

углерод, бор, берилий, литий.

 Вроде вот так. :D

На будущее: В периоде металлические свойства ослабевают (слева направо), так как увеличивается количество электронов на внешнем.

Answer 2

Elements in Increasing Order of Metallic Properties

To arrange the elements in increasing order of metallic properties, we can consider their positions in the periodic table and their atomic structures.

1. Lithium (Li): - Lithium has the least metallic properties among the given elements. - It is a metal with atomic number 3 and is located in period 2 and group 1 of the periodic table. - Source:.

2. Boron (B): - Boron has higher metallic properties compared to lithium. - It is a metalloid with atomic number 5 and is located in period 2 and group 13 of the periodic table. - Source:.

3. Beryllium (Be): - Beryllium exhibits higher metallic properties than boron. - It is a metal with atomic number 4 and is located in period 2 and group 2 of the periodic table. - Source:.

4. Carbon (C): - Carbon has the highest metallic properties among the given elements. - It is a non-metal with atomic number 6 and is located in period 2 and group 14 of the periodic table. - Source:.

Therefore, the elements arranged in increasing order of metallic properties are: Lithium (Li) < Boron (B) < Beryllium (Be) < Carbon (C).
