Based on the electron configuration of sulfur, S, a sulfur atom will gain or lose how many valence electrons when bonding with lithium?

For the lithium atom, $Z=3$; there are 3 positive, nuclear charges. There are 3 extra-nuclear electronic charges, i.e. borne by the 3 electrons, in the neutral atom. Lithium generally loses...

Nitrogen is in Group V. It has 5 . Do I win £5-00?

Well, both magnesium and barium are $"alkaline earths...."$, the which give dications upon oxidation.... ...from Group 2 of . And given Group 2, there are TWO , which are readily...

Main-group tend to form in which the participating atoms are surrounded by $"8 electrons"$. There are many exceptions to the rule, but often we can rationalize the chemistry of the...

In terms of actual , there is literally only one example. You can consider that their oxidation states have never gotten higher than $+8$, except for Iridium: In terms...

It wants the configuration that helium has, which is two . To be more specific, it wants a DUET, not an octet. Beryllium ($"Be"$) has the $4$ (not $2$),...

And the zinc cation is $Zn^(2+)$. When the ions form a salt, clearly they form an electrically neutral species; and thus the formulation of the salt is $Zn_3P_2$. Each phosphorus...

If the sodium is ionised, the outer $3s^1$ electron is lost, so the configuration becomes $1s^2 2s^2 2p^6$, which is the same as neon, $Ne$.

Since the given information is in moles, we need only look at the ratio between the chemicals: Six moles of Li will produce 2 moles of lithium nitride. So, the...

We thus predict that hydrogen sulfide would have a formula of $H_2S$, an analogue of the popular $H_2O$ molecule.
