liraira [26]2 years ago
8 0

Answer:

For example, a wave with a time period of 2 seconds has a frequency of 1 ÷ 2 = 0.5 Hz. A radio wave has a time period of 0.0000003333333 seconds.

The ionic compounds NaClNaCl and MgSMgS are represented by the diagrams above. Which statement correctly identifies diagram 1 an
Oksana_A [137]

Answer:check explanation

Explanation:

No diagram is given above but to determine the value of melting point we need to understand the fact that NaCl has a lower melting point than MgS.

Reasons are; (1) sodium ion (+1) in the first group of the periodic table is characterized by its softness and low melting point and, (2). Is that it has a lower melting point than MgS because the COULUMBIC ATTRACTIONS between its singly charged sodium ions(+1) and the chlorine ions(-1) are weaker than those between the ions in MgS.

Alkaline earth metals are involved in two key diagonal relationships in the periodic table.(a) Give the two pairs of elements in
Molodets [167]

Two alkaline earth metals; Be and Mg exhibit a diagonal relationship. The pair of elements are Be-Al and Mg-Li is Be-Al and Mg-Li.

Six elements make up the majority of alkaline earth metals (Group 2): beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Compared to the elements in Group 1, this group typically contains smooth, silver metals with a less metallic character. Heavy metals like Ca, Sr, Ba, and Ra are equally as reactive as Alkali Metals Group 1 despite sharing many characteristics with that group. All elements found in alkaline earth metals contain two electrons in their valence shells, giving them an oxidation state of +2. This makes it possible for metals to shed electrons with ease, allowing them to create compounds with more stable ionic connections.
