What do the elements in a have in common?

What do the elements in a have in common?

The common feature is that the atoms of all elements consist of electrons, protons, and neutrons.

What do elements in the same groups have in common Why?

Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells. As a result, they will all have the same chemical reactivity.

What do Element 1 and 2 have in common?

Explanation: For the elements in column 1,2 and 13-18 the atoms in the same column have the same amount of outermost electrons, called valence electrons.

What do the elements in group 2 have in common?

The property that is common to all group 2 elements is that they tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.

What should be the most metallic element?

francium
The most metallic element is francium. However, francium is a man-made element, except for one isotope, and all isotopes are so radioactive they almost instantly decay into another element. The natural element with the highest metallic character is cesium, which is found directly above francium on the periodic table.

What is the difference between a family of elements and elements in the same period?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

What 2 elements have the most in common?

Hydrogen and Oxygen are two of the most abundant elements.

What is Group 2 called?

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). In most cases, the alkaline earth metals are ionized to form a 2+ charge.

What is the most active element in Group 17?

FLUORINE
The most active element in Group 17 is FLUORINE.

What do elements in the same family have in common?

All the members of a family of elements have the same number of valence electrons and similar chemical properties.

Which is the least metallic element?

Therefore, the least metallic elements are the opposite: the right and uppermost elements on the periodic table. Thus, the elements Helium, Neon, Fluorine, and Oxygen are logically the least metallic.

What do elements in the same group have in common?

Thus, all the elements of group 16 have the same number of valence electrons (i.e 6) and they show common properties. Example #7 All the elements of 17th group have 7 electrons in its outermost orbit. Elements of group 17 are highly electronegative and have higher ionisation enthalpy.

What are the groups on the periodic table?

In old-style periodic tables, there are two sets of groups numbered I through VIII (typically using Roman numerals). One is designated “A” and the other, “B”.

What do the first two columns of the periodic table have in common?

This answer got 169 “Big Thanks” from other students from places like Hampton or Taylorsville. What do elements in the first two columns of the periodic table have in common? A. They have two valence electrons. B.They tend to lose electrons to gain stability. C. They react strongly with the alkali metals. D.hey do not react with halogens.
