What else can I help you with?
Electrons that are closest to the atom's nucleus are in the blank energy level?
The electron closest to the nucleus has the lowest energy level. Since electrons are attracted to the nucleus, it takes energy to make them orbit at a greater distance (and even more energy to remove them from orbit entirely).
How are emissions of radiation from an atom explained by Bohrs model?
Electrons absorb energy to make electrons move from an lower energy level to a higher energy level. This energy is released as some form of e-m radiation when the electron moves from the higher level to a lower energy level.
How many electrons do the halogens have in their outer most energy level?
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.
How are the electrons arranged in an oxygen atom?
In an oxygen atom, there are 8 electrons arranged with 2 electrons in the first energy level and 6 electrons in the second energy level. This configuration follows the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.
How many electrons fill the outer shell in hydrogen?
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
How many electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.
What terms is used to the electrons in outermost shell or energy level?
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
How do you make a cobalt bohr model?
To create a cobalt Bohr model, first determine the number of protons and electrons in a cobalt atom (27). Place the protons in the nucleus and distribute the electrons in energy levels (shells) around the nucleus, following the rules of Bohr's model. The first energy level can hold up to 2 electrons, the second can hold up to 8, the third can hold up to 18, and the fourth can hold the remaining electrons.
What is the molecule responsible for chemical reactions?
The cell itself is responsible for chemical reactions. Chemical reactions are the basis of life, and all parts of the cell work together to make them happen. Specifically the enzyme and mitochondria are often cited as being responsible. The enzymes are proteins that create a binding surface for the chemical reaction and speed the process. The mitochondria act as a digestive system and energizer for the cell.
How many electrons are in the outer energy level of the atoms of alkali earth metals?
Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.
How many covalent bonds does silicon need to make its outer energy level?
Si has four valence electrons so silicon need to make four covalent bond.
How Which element require the greatest amount of energy to remove an electron?
Core electrons. Probably the 1s level would require the most ionization energy to pull these electrons.
