IF U ANSWER THIS ILL BRAINLIST U N GIVE U 5 STAR. just answer the ones u know if ur a science genius or whateva. ahah ty. 1) what is the electron configuration of oxygen?
a) 2, 6
b) 2, 8, 8
c) 2, 8, 5
d) 2, 2, 2, 2

2) an atom contains 6 protons, u neutrons and 6 electrons. it's atomic number is?
a) 6
b) 7
c) 19
d) 13

3) which of the following statements about atoms is false?

a) an atom is mostly empty space.

b) neutrons and protons are found in the nucleus with the electrons.

c) the number of neutrons found in the nucleus of an atom is always the same.

d) electrons circle the neucleus all the time.

a) 2, 6

a) 6

b) neutrons and protons are found in the nucleus with the electrons.

Explanation:

1.

Electronic configuration entails the arrangement of electrons within an atom. Therefore, to do this, we must know the number of electrons in the element given.

since we have been given oxygen atom, the number of electrons therein is 8.

 So;

    the electronic configuration is 2,6

2.

The atomic number of an atom is the same as the number of protons that it contains. The proton number is the number of positively charged particles in the atom of the element.

Since we have been given that the number of protons within the atom is 6, therefore, the atomic number is 6.

3.

It is false that the nucleus of an atom contains protons, neutrons and electrons. Electrons are not found in the nucleus of any atom. Only the process of electron capture during radioactivity can make this happen.

Electrons are found orbiting the atomic space in discrete energy levels.
