Why atoms tend to lose and gain electrons?
Most atoms do not have eight electrons in their valence electron shell. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations.
Why do metals tend to lose electrons to form positive ions?
The answer is B. Since metals have an excess electrons, so they will give away to become octet.
What tend to form a positive ion?
Metals tend to lose electrons and form positively charged ions called cations. Non-metals tend to gain electrons and form negatively charged ions called anions.
What is needed to pull electrons away from atoms?
All these atoms need is another atom that can attract their electrons! This ability to pull electrons away from other atoms is termed electronegativity. Atoms with a valence shell that is almost full are more likely to be electronegative because they have greater reason to pull electrons towards them.
What type of atoms are good at attracting electrons?
Fluorine is the most electronegative element (type of atom).
What is the most important factor in determining the properties of an element?
Statement I: The most important factor in determining the chemical properties of an elements is the number of electrons in the outermost shell.
What are the factors that determine the position of an element in periodic table?
An element’s location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element’s block.
What is important is determining the chemical properties of an element?
These outer-shell electrons (called valence electrons) are important in determining the chemical properties of the elements. The valence shell electrons in an atom determine the way it will interact with neighboring atoms, and therefore determine its chemical properties.
What property of an element determines the chemical Behaviour?
Answer. Answer: Atomic number . The number of electrons and protons in an atom determines it’s chemical properties..
Which electrons in an atom are the most important for determining chemical and physical properties?
Electrons located in the outermost shell of the electron cloud are called “valence electrons” and have the highest energy. Valence electrons determine the chemical properties of an element, or how the valence electrons of one element are shared or traded with valence electrons of other elements to create new molecules.
