# What is the largest element?

Contents

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

## How do you find the largest element?

To find the largest element,

1. the first two elements of array are checked and the largest of these two elements are placed in arr[0]
2. the first and third elements are checked and largest of these two elements is placed in arr[0] .
3. this process continues until the first and last elements are checked.

Since the atomic radius decreases in a period but increases down the group so Sr of group II and period V is largest in size.

## What is the lightest element on earth?

Hydrogen is the lightest element. Dihydrogen, H2, is a colorless, odorless, tasteless gas.

## How do you order elements from smallest to largest?

We know that atomic size increases from right to left and from top to bottom in the Periodic Table. The smallest atoms are at the top right and the largest atoms are at the lower left of the Periodic Table.

## What is the smallest element?

Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

## Is there a max function in C++?

C++ Algorithm max() C++ Algorithm max() function can be used in following 3 ways: It compares the two values passed in its arguments and returns the larger between them. If both are equal, then it returns the first one.

## Which has the largest radius Co3+ Mn3+ ni3+ Cr3+?

Fe 3+ has highest radii because by going left to right in the periodic table , the size get decreased so .. Fe 3+ >Co3+ >Cr3+ >Mn3+ .

## Which ion has the smallest radius?

As Oxygen is present at the top of the group, therefore, it has the smallest radius due to less number of shells.

## Which of the following has the smallest radius rb K+ K Rb+?

The trend of elemental radius increases from top to bottom and from right to left. This means Rb is greater than K. Incorporating the positive charges, K+ is smaller than K and Rb+ is smaller than Rb. Thus, the trend in increasing order is K+,K,Rb+,Rb.

## Which is the lightest gas in the world?

Hydrogen is the lightest, most abundant and explosive gas on Earth. The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas. It is 220 times heavier than the lightest gas, Hydrogen.

## What is the rarest element in the universe?

Astatine is the rarest naturally occurring element.

## What is the heaviest element known to man?

Heaviest Element in Terms of Atomic Weight

Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289).

## Is Br or Br bigger?

Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.

## Which atom has the smallest size?

atoms

Element Symbol Atomic radius in nanometers
hydrogen H 0.037
helium He 0.05
lithium Li 0.152
beryllium Be 0.111

## Which atom is larger aluminum or phosphorus?

the order of these elements in periodic table is Aluminum, silicon, phosphorus and sulfur. As we know that atomic size decreases from left to right . So, the the element with highest atomic radius is aluminum and then silicon followed by phosphorus and sulfur.
