What 2 subatomic particles are found here? Charge? Size? What subatomic particles are in rings around the nucleus? Charge? Size?

If the atom is neutral, what is the atomic number?

What element is this?

If the atom has the same # neutrons as protons, what would be it’s atomic mass?

If you added another neutron, you would have a different _

If you added another proton, you would have a different _

Which electron- A or B- has more potential energy? Why?

How many more electrons could fit in the outermost shell?

These sheets are subdivided into _ that hold _ electrons each.

Which atomic particle may be lost/gained in chemical reactions? Why would atoms lose/gain them?

Explanation:

neutrons ,0and protons+1,1.11x10^-15

7

nitrogen

14

nucleon number

atomic number

A,the one far from the nucleus

3

electron, to be stable

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

that is true   : ) hope this you
