In what order do electrons fill orbitals within the 3p sublevel? Electrons don’t fill orbitals; protons and neutrons fill orbita

lorasvet [3.4K]

The order do electron fill orbitals within the 3p sublevel is that they spread out, waiting until each orbital has one electron before doubling up.

Explanation

According to hund's rule every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied,and all electrons in singly occupied orbital have the same spin.

when every orbital in a subshell is singly occupied by electrons it is then doubled, and the two electrons in same orbital have opposite spins

Given the following information regarding the masses and relative abundances for the isotopes of an element, determine its atomi

Ilia_Sergeevich [38]

Answer:

Average atomic mass = 58.51047 amu

The symbol is $Ni$

Explanation:

The formula for the calculation of the average atomic mass is:

$Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})+(\frac {\%\ of\ the\ third\ isotope}{100}\times {Mass\ of\ the\ third\ isotope})+(\frac {\%\ of\ the\ fourth\ isotope}{100}\times {Mass\ of\ the\ fourth\ isotope})+(\frac {\%\ of\ the\ fifth\ isotope}{100}\times {Mass\ of\ the\ fifth\ isotope})$

Given that:

For first isotope:

% = 68.274 %

Mass = 57.9353 amu

For second isotope:

% = 26.095 %

Mass = 58.9332 amu

For third isotope:

% = 1.134 %

Mass = 61.9283 amu

For fourth isotope:

% = 3.593 %

Mass = 63.9280 amu

For fifth isotope:

% = 0.904 %

Mass = 63.9280 amu

Thus,

$Average\ atomic\ mass=\frac{68.274}{100}\times {57.9353}+\frac{26.095}{100}\times {58.9332}+\frac{1.134}{100}\times {61.9283}+\frac{3.593}{100}\times {63.9280}+\frac{0.904}{100}\times {63.9280}$

$Average\ atomic\ mass=39.55474 +15.37861854+0.702266922+2.29693304+0.57790912$

Average atomic mass = 58.51047 amu

The symbol is $Ni$

The charges and sizes of the ions in an ionic compound affect the strength of the electrostatic attraction holding that compound

MA_775_DIABLO [31]

Answer:

SrF2>SrO>RbF>CsBr

Explanation:

Ionic solids have their melting points dependent on:

i) size of the the ion: the smaller the size of the ion, the more closely packed the ionic sphere will be and the greater the melting point.

ii) Charge on the ion, the higher the charge on the ion the greater the electrostatic attraction between the ions and the greater the melting point.

In the arrangement above, the order of cation sizes are Sr2+<Rb+<Cs+

the order of anion sizes are F-<O2-<Br-

This explains the order of melting points given in the answer.

A hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as ___.

Klio2033 [76]

A hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as "Heat". When used at home, a fuel cell eliminates the need for "An Electrical grid"

Hope this helps!
