Question

1. Compared to most other metals, what properties do the alkali metals have? А low melting points and high densities B low melting points and low densities C high melting point and high densities D high melting points and low densities​

Answer 1

The alkali metals have low melting points and low densities compared to most other metals due to their large atomic radii and low ionization energies.

Step-by-step explanation:

The alkali metals, such as lithium, sodium, and potassium, have low melting points and low densities compared to most other metals. This is because they have large atomic radii and low ionization energies, which make it easy for them to lose their outermost electron and form stable cations with a charge of 1+. As a result, the alkali metals have weak metallic bonds and are soft, with low melting points and low densities.

Answer 2

B. low melting points and low densities

Step-by-step explanation:

Alkali metals are any of the monovalent elements found in Group IA of the periodic table. They readily lose their one valence electron to form ionic compounds with nonmetals. Examples of alkali metal are Potassium (K), Lithium (L), and Sodium (Na).

Compared to most other metals, the chemical properties that alkali metals have are low melting points (28.5°C) and low densities that is typically less than 1 grams per cubic centimeters.
