Proton number = the atomic number (which is the smaller number
neutron number = the mass number (the bigger number) - the atomic number
number of electrons = the atomic number - the charge (it depends on the element but group 1 is +1 group 2 is +2 group 3 is +3 group five is -3 group six is -2 group seven is -1
i would solve the whole thing but its unclear hope this helps tho
Glaciers are found in areas where the net accumulation of snow exceeds the melt, therefore they are usually found in areas of high elevation, cold temperatures, and high precipitation.
Geysers are found in areas of shallow crust with high heat flow, such as hot spots.
<span>A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule.</span>
Question one should be obvious..
Mass can't be created not destroyed no matter what, so even in a chemical reaction, the answer will remain. The first answer is correct.
Question two
No, because even when water is broken down, there should only be one molecule of oxygen. The fact there is two means it's incorrect.
Question three
Yes. The equation is perfectly balanced on both sides, so it's safe to say the value of mass remains constant.
