Chemistryatomic structure pleas get all right

1. according to bohrs model of the atom in which orbitals do electrons have the most energy?

middle

outermost

innermost orbitals

2. what are valence electrons located

in both the inner and outer electron shells

closest to the nucleus

inside the nucleus

in the outermost electron shell

3. if an electron loses energy what may happens to it

it will never change location

it may drop to a lower energy level 

it may move to a higher energy level

4 who developed the orbital model of the atom

jj thompson

ernest rutherford

mendeleev

niels bohr

5  which of the following subshells can have a maximum of 2 electrons

p

s

f

d

6 consult afbau diagram which shell would be complete with 10 electrons

p

f

s

d

7 consult the perodic table an electrically neutral atom has the folowing electron configuration 1s^2 s ^2  sp^63 s^2 3p^4 what is the name of this atom

selenium

chlorine

phosphous

sulfur

8  what is the electron configuation for an electrically neutral atom of beryllium (Be) use periodic table

9. orbitals are defined by which of the following 

spin direction

composition

energy level

number of electrons

10 the number of electrons in an electrically neutral atom is equivalant to which of the following

number of neutron

atomic number

mass number

atomic weight
