Hydrogen, which is properly a member of the periodic column. If the properties of hydrogen are considered too little like those of the other elements in the this column, the alkali metals, so that only the latter are considered members of column IA, then the answer would be lithium.
What else can I help you with?
What element is in group 1a and higher atomic number than chlorine but lower number than bromine?
The element in Group 1A with a higher atomic number than chlorine but lower than bromine is iodine.
Which element of the group 1A has the largest atom?
Francium (Fr) has the largest atom among the group 1A elements. It has the highest atomic number and electron shells, resulting in a larger atomic size compared to other group 1A elements such as lithium, sodium, and potassium.
What is the ion of an element from group 1 A on the periodic table?
The ion of an element from group 1A on the periodic table will have a +1 charge. This is because elements in group 1A, also known as alkali metals, readily lose one electron to achieve a stable electron configuration, resulting in a positively charged ion.
What is the 1st element?
The first element in the periodic table is hydrogen. It is the lightest and most abundant element in the universe.
What element is lightest the elements?
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
What is the lightest element in group 18 of the periodic table?
Helium is the lightest member in group 18.
What is the lightest element in period of the periodic table?
Helium is the lightest member in group 18.
What element from Group 1A is most reactive?
francium
What group has element with the most diverse set of properties?
penis
Which element has one valence electrons?
Any element in group 1
Why is hydrogen placed with the element in group 1a?
valence electrons and electronic configuration.
What element is in group 1a and higher atomic number than chlorine but lower number than bromine?
The element in Group 1A with a higher atomic number than chlorine but lower than bromine is iodine.
Is boron a compount or element?
Boron is an element. The lightest member of group 13 with 3 valence electrons
Is carbon the lightest element?
No hydrogen is the lightest element.
Which element in 1a group is more reactivity?
Francium(Fr) is the most reactive element in Group 1A . The least reactive is Lithium(Li) The element become increasingly reactive 'down' Group 1A. NB You will NOT find francium in a school lab. for two reasons. 1. It explosive when in contact with water. 2. It is 'Radio-active' and radio-active matter has to be kept in special conditions.
What s block element is not located in group 1A or group 2A in the periodic table?
One example of a block element that is not located in group 1A or group 2A in the periodic table is carbon, which is a p-block element. Carbon is located in group 4A (14) of the periodic table and is known for its diverse bonding properties, forming a wide range of compounds.
Which element of the group 1A has the largest atom?
Francium (Fr) has the largest atom among the group 1A elements. It has the highest atomic number and electron shells, resulting in a larger atomic size compared to other group 1A elements such as lithium, sodium, and potassium.
