Negative ions form when atoms-blank-valence electrons?
Negative ions form when atoms GAIN valence electrons.
What is a blank is a neutral group of atoms held together by covalent bonds?
A blank is a neutral group of atoms held together by covalent bonds.
A chemical bond is what which forces atoms to what?
Chemical bonds are the force of attraction between two atoms. when they combine and form a molecule, they become a new substance with properties similar to that of the "parent" substances. Different amounts of different elements form different substances. You see, when a boy atom likes a girl atom.... just kidding.
How many blank spaces were in mendeleeves periodic table?
There were 3 blank spaces in mendeleev's Periodic Table. He left it for the elements which were not discovered at that time.
Why did mendeleev leave blank spaces on his periodic table?
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
A blank bond occurs when two atoms share electrons to form compounds called molecules?
occurs in gas molecules; also known as diatomic elements.
When atoms in a covalent bond share electrons unequally the bond is said to be blank?
Polar bond
Negative ions form when atoms-blank-valence electrons?
Negative ions form when atoms GAIN valence electrons.
The elements of a group have the sme number of blank in their blank shell?
The elements of a group have the same number of electrons in their outer shell. This similarity in valence electrons is responsible for the similar chemical properties observed among the elements in the same group of the periodic table. For example, elements in Group 1 all have one electron in their outermost shell, leading to their reactivity and bonding characteristics.
The happy atoms are the blank gases They dont react because blank?
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.
When two pairs of electrons are shared between two atoms a ----------------- bond is formed?
When two pairs of electrons are shared between two atoms, a double bond is formed. Each pair of shared electrons represents a bond, so a double bond consists of two pairs of electrons shared between the atoms.
Very few inorganic compounds have atoms in them?
All inorganic compounds have atoms in them. Very few inorganic compounds have carbon atoms in them. (Depending on who you ask, "Very few" might be "No".) It looks like this was a fill-in-the-blank but the blank got eaten.
All atoms have a blank charge?
If there are more protons than electrons there is a positive charge. If there is more electrons than protons there is a negative charge.
Compounds?
Blank has different properties from the elements that formed it, is a pure substance made of 2 or more elements and can be represented by a chemical formula
What is a blank is a neutral group of atoms held together by covalent bonds?
A blank is a neutral group of atoms held together by covalent bonds.
Electrons can be found in energy levels or blank that surround the nucleus of an atom?
the blank is shell
Why was mendeleev work importanr?
Mendeleev, a Russian who enjoyed playing solitaire, marked a set of blank cards with the known elements, then divided them into groups based upon how they combined (i.e. by what we now call "valence"), with "metals" (i.e. electron donors) to the left, and "non-metals" to the left. Next, he arranged each group by weight (or mass), with lighter (less-dense) ones to the top and heavier (denser) ones toward the bottom. What emerged was "The Periodic Table" arranged in eight major columns that reflect the outer "octet" of electrons (with another ten columns interspersed, to account for more-complex atoms that transition from eight to eighteen electrons in the intermediate orbits).
