Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
Beryllium (Be). This is because on the periodic table Be is located in the same group (column) as Calcium and is the highest element in that column. Elements of the same group have similar properties and their masses decrease the higher they are in the group.
Selenium.
elements in the same group as nitrogen will have similar CHEMICAL properties because they have the same number of electrons in the outer shell. (this is according to Bohrs model of the atom, if you want a real confusing answer about valence shells etc. go look at quantam mechanics) So elements in group 7 are phosphurus, arsenic, selenium, tellurium, polonium, these will react with the same chemicals to from similar compounds however they are all solids unlike nitrogen. Elements with similar PHYSICAL properties are elements that are present as gases at room temperature (like nitrogen is) oxygen, fluorine, chlorine, hydrogen and all of group 8 the noble or inert gasses (although inert isn't really a valid term as they can react in the correct conditions)
Potassium. Sodium is in group1 (period2) the next heaviest element is potassium (period 3). Potassium forms salts with the K+ ion.
No silicon is an element in the same group as carbon, it has similar chemical properties but it is not carbon.
Elements in the same family, or group, have similar physical and chemical properties.
Yes.
any element in group !
Buttholes
To find an element that is similar to another element, look in the periodic table and find an element in the same column (group/family) as the element of interest. Usually, elements within the same group/family have very similar properties.
Calcium shares properties with Magnesium and Strontium.
elements in the same group
is it at every tenth element
Elements present within a same group normally have similar properties
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
Only caesium has the same properties as caesium. There are other elements which have some similar properties.
chronium, tungsten, and seaborgium
