What is an electron shell? How many electrons fit in the first, second, fourth
And subsequent shell?

Its due tonight so take your time I guess.

Answers

Answer 1

Answer:

An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n. Electron shells have one or more electron subshells, or sublevels.

Explanation:

The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6), The 4th shell can hold up to 32 electrons.

I don't know the last one though

Answer 2
An electron shell is what surrounds the nucleus of the atoms. The nucleus contains protons and neutrons and is the heaviest part of the atom. Electrons closer to the nucleus will have not have as much energy as the electrons in the outer shells. The first shell can only have two electrons. The second can have 8, of the eight that is broken into sub shells there can be 2 s electrons and six p electrons. The fourth shell or what is also called the valance shell has four subgroups that are s,p,d, and f and all together can have a maximum of 32 electrons. A subsequent shell or sub shell is each electron shell broken into groups. These groups make it so when writing out how many electrons are in atoms you can distinguish how many there are. Along with this, there is a process on how to write these out. The order would be 1s,2s,2p,3s,3p, 4d, 3d, 4p, and so on.

If you use the same force to push a motorcycle as you would to push a bike, which one will have more acceleration and why? Explain using Newton’s Second Law

Answers

Answer:

the bike would because it has  less mass.

Explanation:

im learning newtons laws in class right now so that should be right

The motorcycle right? Because it is experiencing more acceleration by going way faster rather than going too slow?

In which direction does centripetal force act on an object?

in the opposite direction of the tangential speed of the object
in the same direction of the tangential speed of the object
toward the outside of the circle in which the object is moving
toward the center of the circle in which the object is moving

Answers

Answer:

Centripetal force acts on an object toward the center of the circle

in which the object is moving.  That's perpendicular to the object's

tangential velocity.
