C-Rb20
Explanation:
The chemical formula for Rubidium oxide is Rb20.
Hope this helps!
The metric system is based on powers of 10 so it is much easier to convert units, often just by moving the decimal point.
Cola-flavored soda: 2. 6 -Acidic

<h3>What is pH?</h3>
pH value tells us about the acidity and basicity of any solution. pH means potential hydrogen.
The pH scale is counted from 0 to 14 in which 7 is neutral and the value of pure water.
Below 7 are all acids and the above 7 are all basic.
Thus, all acidic substances are Cola-flavored soda: 2. 6, pickle juice: 5. 5, cranberry juice: 2. 9.

Only by measuring the separation between the nuclei of two contacting atoms and halving that distance can one determine the radius of an atom. The illustrations show how the environment around an atom can cause it to have a varied radius, even if it is the same atom.
<h3>How can the atomic size of an element be determined?</h3>
By measuring the distance between the two atoms after two are united, we may determine the atomic size of the new molecule. The third technique for determining an element's atomic size is to create a single covalent link between two atoms and measure the space between them.
Atomic radii in the periodic table change from left to right across a row and from top to bottom along a column. Because of these two patterns, the periodic table's bottom left corner contains the biggest atoms, while the upper right corner has the smallest.
