No they are absolutely not. Na is sodium and K is potassium they have different numbers of protons sodium having 11 and potassium having 19 therefore they are different elements. but because they have one outstanding electron on the last row they react similarly.
Sodium (Na) and potassium (K) belong to the same group on the periodic table, Group 1, which is the alkali metal group. They have similar properties due to being in the same group, but are located in different periods - Na is in period 3 and K is in period 4.
B-Al is different from the other pairs because it consists of elements from different groups in the periodic table. Li-Mg, Na-K, and Ca-Mg are pairs of elements from the same group which exhibit similar chemical characteristics.
K
Two elements that belong to the same group are sodium (Na) and potassium (K), which both belong to Group 1 (also known as the alkali metals) on the periodic table.
Several examples: red-Sr, Li, orange-Ca, yellow-Na, violet- K, white- Ti.
Sodium, Na, is in group 1 on the periodic table. The elements in group1 are the elements in that vertical column, which are Li,Na,K,Rb,Cs,Fr.
These six elements are Li, Na, K, Rb, Cs and Fr.
I think you lost some formatting there. Na+ is isoelectronic with neon, if that's what you were trying to ask.
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
Alkali metals, Li Na K etc
why sodium and potassium lie in the same groups
Rb (Rubidium) is the largest element among Li, Na, Rb, and K as you move down the same group or in the same period from left to right on the periodic table.
