Ineed these asap you c:

1) the outer electrons in an element are referred to as
a) valence electrons
b) ground state electrons
c) excited electrons
d) none of the above

2)in an exothermic reaction, the products have
a) more energy than the reactants
b) less energy than the reactants
c) the same amount of energy as the reactants

3)a static charge is different from an electric current, in that a static charge
a) is a flow of electrons
b) lasts only for a fraction of a second
c) occurs because a force is exerted on the electrons
d) involves the movement of ions as well as electrons

4)the time that it takes for a wave to travel one wavelength is considered a(n)
a) period
b) velocity
c) amplitude
d) rarefaction

(this is for integrated physics and chemisty)

1.

A) valence electrons

Explanation:

outer shell electrons used to participate in formation of bonding because when two atoms comes close to each other then these outer shell electrons interact with each other and hence bond will form between the atoms.

So correct answer will be

A) Valence Electrons

2.

More energy than reactants

Explanation:

Here products will have more energy than reactants due to which overall the energy is released and hence we get some energy along with the products in such type of reactions.

3.

C) occurs because a force is exerted on the electrons

Explanation:

Static charge will remains at rest because of the the force that makes them in stationary condition.

4.

A) Period

Explanation:

One time period is the total time for which a one complete wavelength distance is traveled by the wave.
