Hydrogen, Lithium, and Potassium
yes
the group1 elements
Alkali Metals
Group I elements are called alkali metals as they are generally basic in nature
because dinner has more dinner
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
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.
Here's a simple pseudocode for the divide-into-three algorithm for the fake-coin problem: function findFakeCoin(coins): if length(coins) == 1: return coins[0] // The only coin left is the fake one // Divide coins into three groups group1, group2, group3 = divideIntoThree(coins) weight1 = weigh(group1, group2) // Compare weight of group1 and group2 if weight1 == 0: return findFakeCoin(group3) // Fake coin is in group3 else if weight1 < 0: return findFakeCoin(group1) // Fake coin is in group1 else: return findFakeCoin(group2) // Fake coin is in group2 This pseudocode recursively divides the coins into three groups and uses a balance to identify which group contains the fake coin until it's found.
Group1 is considered Alpha-Numeric because it has both alphabet characters and numeric characters.
Hydrogen is period 1 and group1 element. It has only one electron.
You would get a linear curve because the oxidation state of elements in group 1 increases by one as you move from one element to the next, due to the loss of one electron in their outermost shell. Thus, the plot of oxidation state against atomic number for group 1 elements would result in a straight line.
