What element is in Group 5 Period 7?
Group 5 (by IUPAC style) is a group of elements in the periodic table. Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). This group lies in the d-block of the periodic table.
What are the middle ten groups on the table called?
Additionally, what is Group 8 on the periodic table called? Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). They are all transition metals….Group 3 element.

What element is in Group 15 and Period 4?
Arsenic (As) is an element in group 15.
Why does boiling point increase down the group?
The melting and boiling points increase down the group because of the van der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Does Group 16 gain or lose electrons?
Te is in group 16 so it can gain 2 electrons and have a 2- charge. These two elements can become ions and create an ionic bond. 4. Noble or Inert gases only form ionic bonds with other noble or inert gases.
Which has less boiling point?
helium
Which acid has the lowest boiling point?
p-Hydroxybenzoic acid
Which hydride has more boiling point?
In hydrides of group 16 , H2O has highest boiling point . It is due to extensive H–bonding which exist even in liquid state.
Which has the lowest boiling point at one atmospheric pressure?
Helium
Which of the following has higher boiling point?
Hence, butanol has a higher boiling point. Hydrogen bonding is not possible in butanal.
Why N butanol has higher boiling point?
The greatly increased boiling point is due to the fact that butanol contains a hydroxyl group, which is capable of hydrogen bonding. The result is that butane boils at the temperature at which water freezes (0° C), far below even that of diethyl ether.
Which has higher boiling point aldehyde or ketone?
Amongst aldehydes and ketones, ketones have higher boiling point. This is due to the presence of two electron donating alkyl groups around the C=O. group which makes them more polar. As dipole moment is greater so it is more polar and hence has higher boiling point.
Which has higher boiling point 0.1 m NaCl or 0.1 M glucose?
which has the higher boiling point – 0.1M of NaCl or 0.1M glucose. NaCl: Molar mass = 1 * 23 + 1 * 35.5 = 58.5g. Thus, more is the molarity, less is the BP (ie, volume). Thus, 0.1M of Glucose has lesser BP.
Which NaCl has the highest boiling point 0.1 m?
The boiling point depends only on the Van’t Hoff factor. That means higher the Van’t Hoff factor, higher will be the boiling point and vice-versa. Hence, 0.1 M of NaCl has the higher boiling point.
Which has higher boiling point 0.1 m NaCl or 0.1 m bacl2?
Bacl2 will have higher boiling point as boiling point is a colligative property . And the van’t hoff factor of nacl is more than bacl2. Consequently, 0.1M bacl2 will have higher boiling point than 0.1M nacl.
Which has highest boiling point 0.1 m?
- 0.1 M MgCl2. B.
- 0.1 M HClO4. C.
- 0.1 M KCl. D.
- 0.1 M KOH. E.
- 0.1 M LiNO3. Medium.
- 0.1 M MgCl2. 0.1 M MgCl2 solution has the highest boiling point.
- 1.0 molal aqueous solution of an electrolyte A2B3 is 60 % ionised.
- 18 g of glucose, (C6H12O6) is dissolved in 1 kg of water in a saucepan.
