There are six levels of ecological organization, listed from the smallest to the largest, they are: organism, population, community, ecosystem, biome and biosphere.
The two levels which are made up of members of only a single species are ORGANISMS and POPULATION. Organism refers to any individual living thing while population refers to a group of individual species that live in a specific area at a particular time.<span />

Element A has an electronegativity of 0.8 and element B has an electronegativity of 3.0. Which statement best describes the bond
Advocard [28]

Answer:

C) The compound is largely ionic with A as the cation.

Explanation:

Pulings proposed the method to determine if the compound is ionic in nature or covalent in nature , by finding the difference between the electronegativity of the respective cation and anion .

The ion with higher electronegativity is the anion and the ion with lower electronegativity is the cation.

The electronegativity difference above 1.7 make the compound ionic in nature.

Hence, from the question ,

A is the cation and B is the anion.

And the electronegativity difference above 1.7 so the compound is ionic in nature.

3.Write the symbol of the element that has a charge of +1 when it has 71 electrons.​
tigry1 [53]

The symbol : \tt _{72}^{178}Hf^{+1}

<h3>Further explanation </h3>

There are two components that accompany an element, the mass number and atomic number

Atoms are composed of 3 types of basic particles (subatomic particles): <em>protons, electrons, and neutrons </em>

The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.

Atomic number = number of protons = number of electrons ⇒ neutral number

Atomic mass is the sum of protons and neutrons

Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

The element has 71 electrons and a charge of +1 , so

Number of protons = 71 + 1 = 72

Number of protons = the atomic number = 72

The element with atomic number 72 is Hafnium(Hf)

The atomic mass of Hf = 178 g/mol
