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.

PbO2
You have to take the mass of lead in the problem, and divide by the molar mass.
When you do the same with oxygen, you get a number about twice as large as when you divide the mass of lead by the molar mass of lead. This means that the simplest formula would be PbO2
Answer: Most methods for making new elements involve a cyclotron, which speeds up atoms to high velocities before they smash into other atoms—these atoms are usually of different elements. This causes the nuclei to combine, creating new heavier elements.

Answer:
In plants mitosis takes place throughout life in growing regions called the meristems. Replacements as cells wear out. The cells of the skin and bone marrow are sites of active mitosis replacing skin cells and red blood cells that only have a limited life. Repair.

Answer:
Yes
Explanation:
The virtue that tungsten is metal it means that it does conduct electricity. Tungsten does conduct electricity currents quite well, such as when compared to iron and nickel. It is, however, not a good conductor as compared to other metals though it does get the job done.
