Question

Answer fast please......Based on its position on the periodic table, which of the following properties should beryllium (Be) have?

A. Shiny
B. Low melting point
C. Liquid
D. Poor conductor

Answer 1

A. Shiny

Step-by-step explanation:

The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. It is a fundamental tool in chemistry that helps us understand and study the properties and relationships of different elements.

The periodic table is divided into 18 groups, with one group per column. The first column on the left is group 1, and the last column on the right is group 18. Elements in group 1 are the least stable, whereas elements in group 18 are the most stable.

Beryllium (Be) is in group 2 of the periodic table.

Elements in group 2 are alkaline earth metals. They are harder and less reactive than the alkali metals of Group 1. All group 2 elements have a low electronegativity. They are strong reducing agents, and are also good thermal and electrical conductors. Physically, they are silvery-white, shiny metals. All group 2 alkaline earth metals are solid at room temperature. Compared to the rest of the alkaline earth metals, beryllium has a fairly high melting point, boiling point and atomisation energy.

Answer 2

A. Shiny.

Step-by-step explanation:

Beryllium is a group 2 element, which means that it is an alkaline earth metal. Alkaline earth metals are typically shiny, have low melting points, and are good conductors.

Beryllium is no exception, and it has a melting point of 1287 degrees Celsius and is a good conductor of electricity.

• Option B is incorrect because alkaline earth metals have high melting points, not low melting points.
  Melting point of Beryllium is 1278°C. so we can't say it has low melting point,
  Boiling point of Beryllium is 2469°C.
• Option C is incorrect because alkaline earth metals are solids, not liquids at room temperature.
• Option D is incorrect because alkaline earth metals are good conductors, not poor conductors.

So the answer is A. shiny
