1. 8 (oct means that eight, good way to remember this!)
2. hydrogen has ONE valence electron!

hope this helps :)

Answer:

The octet rule means that atoms need a total of 8 valence electrons to fill their valence shell. Hydrogen only needs two to fill its valence shell.

Explanation:

All atoms except for hydrogen can hold a total of 8 valence electrons in their outer energy levels (2 in the s level, 6 in the p level). Hydrogen only has two electrons total, so it does not require more than the s level and two electrons to have a full valence.

A tank contains a mixture of helium, neon, and argon gases. If the total pressure in the tank is 490. mmHg and the partial press
OleMash [197]

Answer: The partial pressure of neon is 173 mmHg

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

p_{total}=p_A+p_B+p_C

Given : p_{total} =total pressure of gases = 490 mm Hg

p_{He} = partial pressure of Helium = 215 mmHg

p_{Ar} = partial pressure of argon = 102 mm Hg

p_{Ne} = partial pressure of neon= ?

p_{total}=p_{He}+p_{Ar}+p_{Ne}

490=215+102+p_{Ne}

p_{Ne}=173mmHg

Thus partial pressure of neon is 173 mmHg

How many energy levels are partially or fully occupied in a neutral atom of calcium?
mina [271]
18 I think. <span>Essentially because there are so many more orbitals used by the molecules placed in the series. You will see that group 1-8 molecules always have a number of valence electrons equal to the group number. This reflects s and p orbital useage. Once d and f orbitals begin to be needed, the atoms become much more complex.</span>
