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.
What Group 1A elements is the most reactive cesium potassium lithium or sodium?
Cesium is the most reactive Group 1A element because it has the lowest ionization energy and the largest atomic radius, making it more willing to donate its outermost electron in a chemical reaction compared to potassium, lithium, and sodium.
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.
Which is the lightest element in group 1A?
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 element is not a transition element?
any in column 1a, 2a, 3a-8a
How many valence electrons does a group 1A metal atom have?
they all have one valence electron.
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.
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.
What Group 1A elements is the most reactive cesium potassium lithium or sodium?
Cesium is the most reactive Group 1A element because it has the lowest ionization energy and the largest atomic radius, making it more willing to donate its outermost electron in a chemical reaction compared to potassium, lithium, and sodium.
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.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
Which is the lightest element in group 1A?
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.
