Electrons in Bohr's model of the atom are at the lowest possible energy state when they are
arlik [135]

Answer:

d. at ground state

Explanation:

Electrons in the Bohr's model of the atom are at the lowest possible energy state when they are their ground state.

The lowest energy state available to an electron is the ground state.

  • According to the the Bohr's model of the atom, the extranuclear part is made up of electrons in specific spherical orbits around the nucleus.
  • In the excited state, the level is higher than the ground state.
  • When electrons changes state they either absorb or gain energy.

I WILL MAKE YOU BRAINLIEST ! :Which factor varies between the isotopes of an element?
FrozenT [24]
C. The neutron number.

An element is determined based on how many protons has, if the protons number change then you got a new element.

If the number of neuron change you got the same element except it will be a bit heavier or lighter if you are gaining or loosing neutrons. Those variations of an element are called the isotops of the element.

The protons and neutrons toghether form the nucleus of the atom that is heavy and dense as an elephant.

The electrons are light as fleas and stay on the shels of around the nucleus and if they are more then the number of protons they make the atom negatively charged and vice versa.

Calculate the number of moles in a 14.5 gram sample of C4H10.
cricket20 [7]
Moles= mass divided by molar mass
Molar mass= 12.01(4) + 1.01(10)
                 = 58.14g/mol

Moles=14.5g / 58.14g/mol
         =0.249

Therefore there are approx 0.249 moles in a 14.5g sample of C4H10
