Answer:
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
<span>D. the angle of their slope is greater than 40 degrees.
</span>Oversteepened slopes often lead to mass movements because <span>the angle of their slope is greater than 40 degrees.
</span>
NOT:
A. the angle of their slope is between 50 and 60 degrees.
<span>B. plants cannot grow on them. </span>
<span>C. the angle of their slope is less than 50 degrees. </span>
For for the formulas with the abbreviated names of the ions, you switch the exponents for each one, so for number 2 it would be Fe2O3 or for 6 it would be CaCl2
For the compounds, you take the abbreviated names of the ions from the periodic table and wherever the ion falls, that’s how many electrons it has and so it would need more ions to make the full shell, so for sodium chloride, since both need one, it would be NaCl or for tin (ll) fluoride, it would be SnF2
Answer:
plutonium
Explanation:
Since the mass of plutonium is higher than any other one on the chart this means it can withstand more pressure such as being used in architecture
