What element has the least attraction for electrons?

Electrons closer to the center are held more tightly as proton number increases. However, outermost electrons are held less tightly because inner electrons shield them. For this reason, it is astatine that has the least attraction for its outer electrons. It also has the least tendency to gain more.

Which atom has the strongest attraction for electrons?

Explanation: Fluorine has the greatest attraction for electrons in any bond that it forms. The attraction of an atom for shared electrons is called its electronegativity.

Which group 17 element has the weakest attraction for electrons?

Halogens are nonmetals in group 17 (or VII) of the periodic table. Down the group, atom size increases. As a diatomic molecule, fluorine has the weakest bond due to repulsion between electrons of the small atoms. Due to increased strength of Van der Waals forces down the group, the boiling points of halogens increase.

Which element has largest atom?

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.

What element has most electrons?

Oganesson has the highest atomic number and highest atomic mass of all known elements….

Electrons per shell 2, 8, 18, 32, 32, 18, 8 (predicted)
Physical properties
Phase at STP solid (predicted)

Which atom has the weakest attraction for hydrogen?

Which atom has the weakest attraction for the electrons in a bond with an H atom? Sulfur has 2.6 electronegativity. Oxygen has a 3.4 electronegativity which is greater than nitrogen which has 3.0 electronegativity.

How many bonds can group 17 make?

Oxygen and other atoms in group 6A (16) obtain an octet by forming two covalent bonds….How Many Covalent Bonds Are Formed?

Atom (Group number) Number of Bonds Number of Lone Pairs
Fluorine (Group 17 or 7A) 1 3

What is the most expensive element in the world?

As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium.

Who is the smallest element?

Thus, helium is the smallest element, and francium is the largest.

Is element 119 possible?

Density (near r.t. ) Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. It is the lightest element that has not yet been synthesized.
