Some people think its francium and some people believe it is either sodium or potassium.
Some people believe that the most reactive element is francium because the larger the atom, the easier it is to get rid of the valence electrons and the easier it is to react with other atoms. so now if you look at the periodic table, francium has the largest radius and so that's why some people think its francium. but in my opinion, Francium AND Cesium.
Answer:
Mass = 14.876 g
Explanation:
Given data:
Volume of gold = 0.77 cm³
Mass of gold = ?
Solution:
Density of gold from literature is 19.32 g/cm³
Formula:
d = m/v
d = density
m = mass
v = volume
by putting values,
19.32 g/cm³ = m/ 0.77 cm³
m = 19.32 g/cm³ × 0.77 cm³
m = 14.876 g
scandium. if you look up the number of electrons thats the periodic number and it gives you the answer
Hey there!
When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.
Hope this helps! :)
<span>An example of sublimation is when a dry ice changes to carbon dioxide when kept in an open container. Sublimation is a change from solid phase to gas phase without passing through the liquid state. In this example, it is clear that the dry ice is solid form and it evaporates as gas without passing through the liquid state.</span>
