What determines how elements will interact with each other?

The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.

What causes atoms elements to react with one another?

Atoms form chemical bonds with other atoms when there’s an electrostatic attraction between them. This attraction results from the properties and characteristics of the atoms’ outermost electrons, which are known as valence electrons.

How is it possible for atoms to react?

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

What information on the periodic table lets you predict the number of electrons in an atom?

What information on the periodic table lets you predict the number of electrons in an atom? The amount of electrons are equal to the number of protons, the atomic number.

How do you know if two elements will react?

When deciding if a replacement reaction will occur, look up the two elements in question. The higher one will replace the lower one. Elements in the middle of the list will react with acids (but not water) to produce a salt and hydrogen gas. Elements at the bottom of the list are mostly nonreactive.

Which elements react most easily with each other?

The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.

What is formed when two atoms combine?

When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.

How do atoms of different elements combine together?

Explanation: Atoms of different elements can combine to make new substances. A molecule is formed when two or more atoms join together chemically. … When two hydrogen atoms combine with one oxygen atom, it becomes the compound water.

What happens when 2 atoms collide?

In an atomic collision, an electron orbiting one atomic nucleus may influence what happens to an electron on the other atomic center. For example, the Coulomb repulsion between the two electrons may cause one or more of the electrons to change state.

What would happen if two atoms collide?

Originally Answered: What happens if 2 atoms collide? If the outer (valence) shells of the colliding atoms are capable of forming a chemical bond that will occur. If not, the two atoms will probably rebound and continue to circulate.

What information on the periodic table lets you predict the number of electrons in an atom quizlet?

a) The group number of an element in the periodic table indicates the number of the electrons in its outermost orbit.

What information on the periodic table lets you predict the number of protons?

The element symbol is always almost accompanied by other information such as atomic number and atomic weight. Atomic number describes the number of protons in one atom of that element.

How can the periodic table predict the properties of new elements?

The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. Creating new elements is not a simple process. Scientists use a particle accelerator to smash light atoms into a thin metallic foil that contains heavier atoms.

Why is the atomic theory generally accepted as a fact?

After all, the atom cannot be seen, even with electron microscopes — yet its behavior can be studied in terms of its effects. Atomic theory explains a great deal about the universe, including the relationship between chemical elements, and therefore (as with Darwin’s theory concerning biological evolution), it is generally accepted as fact.

How do atoms of the same element have the same atomic number?

Atoms of the same element always have the same number of protons, and since this figure is unique for a given element, each element is assigned an atomic number equal to the number of protons in its nucleus. The atoms are listed in order of atomic number on the periodic table of elements. ATOMIC MASS AND ISOTOPES.

Why does each chemical reaction need to be balanced?

Due to the law of the conservation of matter, each chemical reaction needs to be balanced to ensure that the same number and types of atoms on the left side of the equation are the same as on the right side of the reaction.
