Is iodine in the alkali metal family?

Is iodine in the alkali metal family?

Two Groups Of Elements: The halogens are nonmetals that are located in group 17 on the periodic table, and the alkali metals are found in group 1. Halogens include fluorine, chlorine, bromine, iodine and astatine. Alkali metals include lithium, sodium, potassium, rubidium, cesium and francium.

What metals are in the alkali metal family?

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

What family does iodine belong to?

The Halogens
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name “halogen” means “salt former”, derived from the Greek words halo- (“salt”) and -gen (“formation”).

Which element belongs to the alkaline family?

Who’s in the family? The members of the alkaline earth metals include: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). As with all families, these elements share traits. While not as reactive as the alkali metals, this family knows how to make bonds very easily.

What makes the alkali metals a family?

The alkali metal family is found on the periodic table in Group 1, which is on the far left side of the table. The metals in this group are lithium, sodium, potassium, rubidium, cesium, and francium. The gas hydrogen is also put in this group because it shares similar reactivity with the alkali metals.

Which element is not a member of the alkali metal family?

Hydrogen
Hydrogen is a very special element of the periodic table and doesn’t belong to any family. While hydrogen sits in Group I, it is NOT an alkali metal.

Is iodine a metal or non metal?

Iodine is a non-metallic, dark-gray/purple-black, lustrous, solid element. Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements.

Is iodine paramagnetic or diamagnetic?

Magnetic Type of the elements

Hydrogen	Diamagnetic	Niobium
Sodium	Paramagnetic	Antimony
Magnesium	Paramagnetic	Tellurium
Aluminum	Paramagnetic	Iodine
Silicon	Diamagnetic	Xenon

Which elements make up a family?

5 Element Families

• Alkali metals.
• Alkaline earth metals.
• Transition metals.
• Halogens.
• Noble gases.

What kind of elements are in the alkali metal family?

The highlighted elements of the periodic table belong to the alkali metal element family. The alkali metals are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family.

What are the atomic numbers of alkali metals?

Alkali Metals. Name: Lithium. Symbol: Li. Atomic Number: 3. Atomic Mass: 6.9. Number of Protons/Electrons: 3. Number of Neutrons: 4. Classification: Alkali Metals. Discovery: 1817.

What makes an alkali metal an electropositive element?

1 Alkali metals have one electron in their valence shell. 2 The electronic configuration is given by ns 1 . 3 They tend to lose the outer shell electron to form cations with charge +1 (monovalent ions). 4 This makes them the most electropositive elements and due to the same reason, they are not found in the pure state.

How many element families are there on the periodic table?

9 Element Families Another common method of categorization recognizes nine element families: Alkali Metals: Group 1 (IA) – 1 valence electron Alkaline Earth Metals: Group 2 (IIA) – 2 valence electrons Transition Metals: Groups 3-12 – d and f block metals have 2 valence electrons
