From the periodic table, we can see that:
At ground state, the hydrogen atom has one electron
Based on the electronic configuration, at ground state this electron should be occupying the orbital (1s)
Since (1s) is not one of the choices, therefore, the answer is "none of the above"
Answer:
As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals. The alkaline earth elements are metallic elements found in the second group of the periodic table.
I say the answer is The ratio of oxygen atoms to hydrogen atoms in a molecule of sugar is 2 to 1
The statement above is a limitation of the kinetic molecular theory. Kinetic molecular theory is a theory which is based on the assumption that gases are made up of large number of particles which behave like spherical objects in a state of constant, random motion in space. These particles move in a straight path until they collide with another particle or the wall of the container.
The planet is Venus. it spins the opposite way.
