The iPad runs on Apples custom-designed silicon A4 chip. It is 1 GHz (a unit used to measure processor speed). It now also runs on iPhone 4 and iPod touch 4.
1/4 + 1/4 + 1/4 + 1/4 = 4/4 = 1/1 = 1
What are you asking? 1 + 1 + 4 is 6 in total. 1 x 1 x 4 is 4 in total. 1 / 1 / 4 is 1/4 in total.
Silicon has 4 valence electrons because it is in group 14 of the periodic table, which means it has 4 electrons in its outer shell. Chlorine has 7 valence electrons but gains 1 electron from another atom to achieve a stable octet configuration, resulting in a valency of 1.
Tetrachloride has a valency of 4 as it has four chlorine atoms attached to a central atom. The symbol for tetrachloride can vary depending on the central atom. For example, carbon tetrachloride is CCl4, while silicon tetrachloride is SiCl4.
Silicon has 4 valence electrons, calcium has 2 valence electrons, chlorine has 7 valence electrons, and sodium has 1 valence electron.
To find the amount of chlorine needed to combine with silicon to form silicon tetrachloride, first calculate the molar masses of silicon and chlorine (28.09 g/mol and 35.45 g/mol, respectively). As silicon tetrachloride has a 1:4 ratio of silicon to chlorine, this means 1 mole of silicon (28.09 g) will react with 4 moles of chlorine (4 * 35.45 g) to form silicon tetrachloride. Therefore, to find the grams of chlorine needed to combine with 24.4 grams of silicon, calculate (24.4 g Si / 28.09 g Si) * (4 moles Cl * 35.45 g Cl).
Atomicity, what a charming old word. Used to mean either valency or the number of atoms in a molecule. For silicon the valency is 4. (where valency was the numebr of bonds that could be formed) Silicon is not molecular, it is normally encountered as a solid with a network lattice.
The valency of the silicate ion is -4, meaning it has a charge of -4. This is because the silicate ion is made up of one silicon atom (which has a valency of +4) and four oxygen atoms (each with a valency of -2).

Sodium (Na) typically has a valency of +1 because it has one electron in its outer shell, which it tends to lose to achieve a stable electron configuration. In a NaCl crystal, sodium loses one electron to chlorine (Cl), which has a valency of -1, resulting in an overall neutral compound with a 1:1 ratio of Na and Cl ions.
i think 4 is the valency of tetrachloride
Silicon belongs to the Group 14 elements in the periodic table, meaning it has 4 valence electrons as carbon does. However, silicon's larger atomic size allows it to accommodate additional electrons in its outer shell, resulting in a co-valency of 6. Carbon, on the other hand, is smaller in size and can only effectively bond with a maximum of 4 other atoms.
One atom of silicon can combine with four atoms of chlorine to form silicon tetrachloride (SiCl4).
The value of N in silicon tetrachloride (SiCl4) is 4. This indicates that there are 4 chlorine atoms bonded to the central silicon atom in the molecule.
