What do all elements in the same family have?
The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
What are the family names on the periodic table?
Group
- Group 1: alkali metals, or lithium family.
- Group 2: alkaline earth metals, or beryllium family.
- Group 3: the scandium family.
- Group 4: the titanium family.
- Group 5: the vanadium family.
- Group 6: the chromium family.
- Group 7: the manganese family.
- Group 8: the iron family.
Why are elements put into families?
The columns of the table represent groups, or families, of elements. The elements in a group often look and behave similarly, because they have the same number of electrons in their outermost shell — the face they show to the world. Metal elements are usually good conductors of electricity and heat.
What are 3 elements in the same period?
The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon. The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block….Period 3 element.
| Hydrogen | Rubidium |

| Strontium | |
| Yttrium | |
| Zirconium | |
| Niobium |
How do you know what family your element is in?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What are the 10 families of elements?
This product includes eight mini- posters, one for each of the element families on the main group of the periodic table: Alkali Metals, Alkaline Earth Metals, Boron/Aluminum Group (Icosagens), Carbon Group (Crystallogens), Nitrogen Group (Pnictogens), Oxygen Group (Chalcogens), Halogens, and Noble Gases.
Which family of elements does not react with oxygen?
noble metals
Which element is highly reactive?
Reactivity of Group 1 Elements Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
How can you tell which metal is more reactive?
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
Which block is highly reactive?
s-block elements
Is oxygen highly reactive?
Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. As such, it readily forms compounds (notably oxides) with almost all other elements.
What are the 3 properties of oxygen?
The Physical Properties of Oxygen are as follows:
- Color : Colorless.
- Phase : Gas.
- Odor : Oxygen is an odorless gas.
- Taste : A tasteless gas.
- Conductivity : A poor conductor of heat and electricity.
- Solubility : Slightly soluble in water, alcohol and some other common liquids.
- Density : It is denser than air.
What is oxygen highly reactive with?
Alkali metals
Is oxygen more reactive than chlorine?
Despite being less electronegative than oxygen and fluorine, chlorine has the highest electron affinity of any element. Also oxygen is normally found in its triplet state which has a barrier to reacting with singlet species (most organic compounds). Singlet oxygen is more reactive than chlorine I believe.
Which is more reactive N or NE?
Neon: 1s2, 2s2, 2p6. As we can see from the electronic configurations, neon has a fully filled outer shell and hence is non-reactive. Hence, it is much easier for oxygen to complete its octet, as compared to nitrogen and that is why, oxygen is more reactive than nitrogen.
Which of the following is the most reactive?
Fluorine is the most reactive element among the given elements.
Why oxygen is more oxidizing than chlorine?
Explanation: concept : In group , oxidizing power { means tendency to gain electron } decreases from top to bottom as the size increases . Oxygen is more electronegative than Cl , hence, O is stronger oxidizing agent than Cl.
Can chlorine oxidize oxygen?
Originally Answered: is chlorine gas a stronger oxidizing agent than oxygen gas? Yes, chlorine’s a stronger oxidizing agent.
What is the strongest oxidant?
The strongest oxidant in the table is F2, with a standard electrode potential of 2.87 V. This high value is consistent with the high electronegativity of fluorine and tells us that fluorine has a stronger tendency to accept electrons (it is a stronger oxidant) than any other element.
Which is the strongest reducing agent?
Lithium
