Why does only phosphorus have valency more than 4?
No. Nitrogen does, as well.

How does iPad Function?
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.
What is the moleclar shape of SiBr4?
Tetrahedral, just like methane. The 'Si' (Silicon) is immediately below Carbon in Group 4. So it behaves very similarly to carbon . Silicon , like carbon has four outer most electrons in its outer energy shell , so it will make four bonds. One each to each of the Bromines (Br). Silicon like carbon has the ability to catenate, that is form chains by bonding to itself. This feature is not as strong in silicon. The crystalline structure of sand ( silicon dioxide) is such that silicon bonds to itself and to oxygen.
How do you write four quarters infraction?
1/4 + 1/4 + 1/4 + 1/4 = 4/4 = 1/1 = 1
Why silicon have 4 valency and chlorine 1?
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.
What is the valency and symbol of tetrachloride?
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.
How many valence electrons do the silicon calcium chlorine and sodium have?
Silicon has 4 valence electrons, calcium has 2 valence electrons, chlorine has 7 valence electrons, and sodium has 1 valence electron.
How many grams of chlorine are required to combine with 24.4grams of silicon to form silicon tetrachloride?
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).
What is atomicity of silicon?
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.
What is the valency of silicate ion?
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).
What is the atomicity of silicon?
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.
Why the valency of Na is not 4 in NaCl crystal?
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.
What is the valency of tetrachloride?
i think 4 is the valency of tetrachloride
Why is the co-valency of silicon 6 whereas that of carbon is 4?
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 properly be combined in a compound with how many atoms of chlorine?
One atom of silicon can combine with four atoms of chlorine to form silicon tetrachloride (SiCl4).
What is N for silicon tetrachloride SiCI4?
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.
