Write the chemical symbols for three different atomic cations that all have 14 protons
2 answers:
The symbols for three different cations with 14 protons are Si²⁺, Si⁴⁺, and Si³⁺.
An element with 14 protons must be <em>silicon, S</em>i.
Its electron configuration is [Ne] 3s²3p², so it could lose up to four valence electrons.
The most likely cations are Si²⁺, Si⁴⁺, and Si³⁺ (or Si⁺).
Answer:
The cations are 
Explanation:
Atomic number = Number of protons present in the nucleus of an atom of the element
Number of protons =14
Atomic number of an element will be 14.
The name of the element with 14 atomic number is silicon. It has equal number of electrons. Since an atom is a neutral species.
After loosing electrons atom gain positive charge.
![[Si]=1s^22s^22p^63s^23p^2](https://tex.z-dn.net/?f=%5BSi%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E2)
After losing an electron is becomes 
![[Si^+]=1s^22s^22p^63s^23p^1](https://tex.z-dn.net/?f=%5BSi%5E%2B%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E1)
After losing 2 electron is becomes 
![[Si^{2+}]=1s^22s^22p^63s^23p^0](https://tex.z-dn.net/?f=%5BSi%5E%7B2%2B%7D%5D%3D1s%5E22s%5E22p%5E63s%5E23p%5E0)
After losing 3 electron is becomes 
![[Si^{3+}]=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BSi%5E%7B3%2B%7D%5D%3D1s%5E22s%5E22p%5E6)

Explanation:
Alkali metals.
Elements found in group 1 of the periodic table.
F = (mass)(acceleration) = ma
m = 55 kg
Vi = 20 m/s
t = 0.5 s
Vf = 0 m/s (since she was put to rest)
a=(Vf-Vi)/t
a=(0-20)/5
a = 40 m/s^2 (decelerating)
F = ma = (55 kg)(40 m/s^2)
F = 2200 N
Answer:
6.022 x 1023 molecules = 1 Mole O2 = 22.4L
3.022 x 1023 molecules = 1/2 Mole O2 = 11.2L
The answer is 11.2 Litres
