What is the name for NaCO3?
Sodium (Na) Carbonate (CO3). Although, this technically doesn't
exist - it is Na2CO3, because sodium has a valency of 1 and the
carbonate ion has a valency of 2.
Asked in Elements and Compounds
How many bonds are in sodium?
Sodium has a valency of one. It loses one electron to become the
Na+ ion. In the metal the sodium atoms are bonded with a metallic
bond involving the delocalistion of the alenc electrons across a
lattice of sodium ions.

If Na2O is sodium Oxide what is NaO?
it is called the sodium monooxide but it is unstable as oxygen
has -2 valency and sodium has +1
Asked in Elements and Compounds
How do you find the chemical formula of sodium oxide?
Well you should know the formula and valency of each element
first,
Sodium
formula - Na
valency - +1
Oxide
formula - Oxygen - O
valency - (-2)
Since the charge of the compound has to be 0 (zero)
2 atoms of sodium (+2) are required to neutralize the effect of
the one oxygen atom (-2) ----------- [2 + (-2) = 0]
Na2O
Asked in Elements and Compounds
Does hydroxide have valency?
Yes, hydroxide has a valency of 1.
So sodium hydroxide - NaOH - is a compound with Na having a
valency of 1 and hydroxide having a valency of 1. For calcium
hydroxide, in which calcium (Ca) has a valency of two (2), the
formula is Ca(OH)2.
Asked in Elements and Compounds
When sodium burns in chlorine gas what substance is formed?
Sodium Chloride, NaCl, or table salt.
The reactive, valency one sodium combines with the also reactive
gas chlorine, and they become an ionic compound.
Asked in Chemistry, Elements and Compounds, Chemical Bonding, Salt (Sodium Chloride)
How do bond is formed in NaCl?
NaCl is also known as sodium chloride. Sodium has valency +1 and
Chlorine has valency -1. So, sodium donates one electron to
chlorine and thus sodium becomes electrically positive and chlorine
become electrically negative. They is a strong force called
electromagnetic force which attracts each other. Thus, the bond
formed is a ionic bond.

Asked in Elements and Compounds
Why do you need two sodium atoms for every oxygen atom?
In sodium oxide there are two sodium atoms for each oxygen,
formula is Na2O. The reason is that oxygen has a valency of 2 and
sodium has a valency of one. They form an ionic compound with two
Na+ ions to each O2- . In both of these different sorts of ions the
outer electron shell is the same as a noble gas--sodium loses one
electron to get the outer shell configuration of Neon and oxygen
gains two electrons to get the outer shell configuration of Neon
.

What is variable valency of an element?
this is when an atom has more than one valency
for example, iron can have a valency of 2, if it is iron (II),
or similarly, it can have a valency of 3, if it is iron (III)
Asked in Chemistry
What is valancy?
VALENCY-valency is the number of one atom of a given
element can form.
