The chemical symbols for three different atomic cations that all have 19 protons : [Ca+] and [Sc2+] and [Ti3+]

Calcium:

Calcium have 20 electrons or it have 20 atomic number. Since an atom is a neutral species.

[Ca] = (1s2) (2s2) (2p6) (3s2) (3p6) (4s2)

After losing one electron atom gain positive charge and is become

[Ca+] = (1s2) (2s2) (2p6) (3s2) (3p6) (4s1)

Scandium:

Scandium have 21 electrons or it have 21 atomic number. Since an atom is a neutral species.

[Sc] = (1s2) (2s2) (2p6) (3s2) (3p6) (4s2) (3d1)

After losing two electron atom gain positive charge and is become

[Sc2+] = (1s2) (2s2) (2p6) (3s2) (3p6) (4s1)

Titanium:

Titanium have 22 electrons or it have 22 atomic number. Since an atom is a neutral species.

[Ti] = (1s2) (2s2) (2p6) (3s2) (3p6) (4s2) (3d2)

After losing three electron atom gain positive charge and is become

[Ti3+] = (1s2) (2s2) (2p6) (3s2) (3p6) (4s1)

Tried solving this multiple ways, but keep getting the wrong answer. So, I would appreciate the help. Thank you.

Aliun [14]

Answer:

I can give you the definition ... That might help cause I honestly don't kno the answer either ;-;

Explanation:

When used as a diacritic mark, the term dot is usually reserved for the interpunct, or to the glyphs 'combining dot above' and 'combining dot below' which may be combined with some letters of the extended Latin alphabets in use in Central European languages and Vietnamese.

Here is an example:

The dot product between a unit vector and itself is also simple to compute. In this case, the angle is zero and cosθ=1. Given that the vectors are all of length one, the dot products are i⋅i=j⋅j=k⋅k=1.

How does the density of a gas depend on the molar mass of the gas?

AlladinOne [14]

Answer:

The density of the ideal gas is directly proportional to its molar mass.

Explanation:

Density is a scalar quantity that is denoted by the symbol ρ (rho). It is defined as the ratio of the mass (m) of the given sample and the total volume (V) of the sample.

$\rho = \frac{m}{V}$ ......equation (1)
