Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
Ti has the configurate [Ar]4s2,3d2 so it has 2 electrons in its outer shell
The number of valence electrons is dependent on which group of the periodic table the element is in.Since Argon is in group 8, it has a total of 8valence electrons.
Iron has an electronic configuration of [Ar] 3d6 4s2. Both outer shells (3 and 4 are incomplete - this is typical for the transition metals, and explained by the aufbau principle. In theory you would need an additional 4 electrons to fill the 3d shell (making it d10), and additionally 6 p electrons, 10 d electrons and 14 f electrons to fill the 4th What happens in practise is the iron has common oxidation states of 2 (losing the 4s2 electrons) and 3 (additionally losing one d electron).
Calcium atoms have two electrons in the s orbital of their outermost energy level. Their electron configuration is [Ar]4s2.
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
Eight.
Ti has the configurate [Ar]4s2,3d2 so it has 2 electrons in its outer shell
He :The number of electrons in an atom's outer electron shell determines how many dots there are. Helium has 2 electrons in its outer electron shell, so 2 dots.
Germanium is a group 14 element. It's electron structure is [Ar] 3d10 4s2 4p2. Therefore, it has 2 electron's in its outer shell.
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
The number of valence electrons is dependent on which group of the periodic table the element is in.Since Argon is in group 8, it has a total of 8valence electrons.

Five electrons. Gallium has an electronic configuration of [Ar] 4s2 3d10 4p1 The outer shell can be considered full when it is the same as the noble gas in the same period, Krypton, which has the configuration [Ar] 3d10 4s2 4p6
Calcium has 2, 8, 8, and 2 electrons in its shells. The particulars are here: http://en.wikipedia.org/wiki/Calcium
Calcium atoms have two electrons in the s orbital of their outermost energy level. Their electron configuration is [Ar]4s2.
Yes, they have stable electron configuration i.e, their outer most shell has all its valence electrons filled.Some famous noble gases areHelium (He)Neon (Ne),Argon (Ar),Krypton (Kr),Xenon (Xe),and the radioactive Radon (Rn).
