Answer:

Ok,for some animals to survive,then ww should first look at the kind of ecosystem they ate exposed to.

So first for some animals to survive,some of them will have to migrate,and so migration in a given set up of an ecosystem,the other animals may lack food as in they depend on the migrating animals as their prey hence their food.

Secondly,hibernation some animals may hibernate due to intensive weather or climate change which is inevitable,and this might affect other animals in such a way that may lead to decrease of their counterparts hence dying due to an imbalance as the other animals may become prey to the predators available.

Which of these elements has an atom with the most stable outer electron configuration? * Cl Ca Ne Na
SashulF [63]

Answer:

Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure

Explanation:

The configuration of these elements is as follows;

Cl₁₇ = 2, 8,7 (the outer electron is 7)

Ca₂₀ = 2,8,8,2 (the outer electron is 2)

Ne₁₀ = 2,8 (the outer electron is 8)

Na₁₁ = 2,8,1 (the outer electron is 1)

Based on the outer electron value above, Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure.

Give the nuclear symbol for the isotope of gallium, ga, that contains 40 neutrons per atom. Replace the question marks with the
Cerrena [4.2K]

The nuclear symbol of an element have three parts namely:  

  1. the symbol of an element
  2. mass number of the element
  3. atomic number of the element

The general representation is as:

_{Z}^{A}X

where X is the chemical symbol of the element, A is mass number of the element that is total number of neutrons and protons in the nucleus of an atom, and Z is atomic number of the element that is number of protons in the atom.

Element = Gallium, Ga    (given)

Number of neutrons = 40 (given)

Let the nuclear symbol be _{?}^{?}Ga. So, we need to determine the values of "?" in the symbol.

Atomic number of Gallium, Ga = 31

Since, atomic number = Number of protons.

So, number of protons of Gallium, Ga = 31

Mass number = number of protons + number of neutrons

Substituting the values:

Mass number = 31+40 = 71

So, the nuclear symbol is _{31}^{71}Ga.
