True or false . in a covalent bond the atom are held together by the attractions between the shared electrons and protons in each nucleus?
False. In a covalent bond, atoms are held together by the sharing of electrons between their outer energy levels, not by attractions between shared electrons and protons. This sharing creates a stable electron configuration for both atoms.
What is the strength of attraction between a nucleus and the outermost electrons?
The strength of attraction between a nucleus and the outermost electrons is determined by the electric charge of the nucleus (protons) and the distance between the nucleus and the electrons. This attraction is the basis for the force that holds atoms together and is essential for the stability of matter.
What do the number of protons and the strength of the attractions of electrons to the nucleus influence?
The properties of the atom
What do number of protons and the strength of the attractions of electrons to the nucleus influence?
The properties of the atom
What is a nuecleus orbited by?
A nucleus is orbited by electrons in an atom. Electrons are negatively charged particles that move around the positively charged nucleus in specific energy levels or orbits. The interaction between the electrons and the nucleus holds the atom together.
Why do force of attraction between nucleus and electrons decrease in alkali metal as increase in size?
As alkali metals increase in size, the distance of the outermost electrons from the nucleus increases. The attraction between the electrons and the nucleus is electrostatic, and it is a fundamental property of electrostatic attractions that the attraction decreases with increasing distance between the attracting charges. Another way of describing this is that the attractive force is partially "screened" by the inner electrons between the outermost electrons and the nucleus.
What holds an atom together?
An atom is held together by the strong nuclear force, which overcomes the electrostatic repulsion between positively charged protons in the nucleus. This force keeps protons and neutrons together in the nucleus, while electrons are attracted to the nucleus by the electromagnetic force.
What is the force that hold atoms together in a covalent bond?
Covalent bonds are held together by electrostatic (+/-) attractions between the nucleus of one atom and electrons from another atom and vice versa and there is also a quantum mechanical effect of delocalisation.
What is found between the electrons and the nucleus in an atom?
The space between the electrons and the nucleus in an atom is filled with empty space and the nucleus contains protons and neutrons.
What is the region between the nucleus and the electrons in an atom called?
The region between the nucleus and the electrons in an atom is called the electron cloud.
What is the effect of the electromagnetic and strong force on he structure of the atom?
The electromagnetic force is responsible for holding the electrons in orbit around the nucleus of an atom, due to the attraction between positive protons and negative electrons. The strong nuclear force is responsible for binding protons and neutrons together in the nucleus, overcoming the electrostatic repulsion between positively charged protons. Together, these forces determine the structure and stability of an atom by balancing the interactions between the nucleus and electrons.
What are atoms of covelent bond held together by?
... fact that some electrons of the atoms forming a covalent bond can occupy a lower energy orbital, created by sharing the thus bonded electrons between or among the influence of two or more nuclei of the bonded atoms, than the thus-shared electrons can occupy in the individual atoms from which they came into the covalent bond.
