What is necessary for a metallic bonds to form

Metallic bonds can occur between different elements to form alloy. In contrast to electrons that participate in both ionic and covalent bonds electrons are that participate in metallic bonds delocalize forming a sea of electrons around the positive nuclei of metals.

The electrons must be attracted to each other.

Explanation:

The complete question is:

"What is necessary for a metallic bond to form?

The atoms should be in close proximity.

The atoms should be far apart.

The electrons must be attracted to each other.

The nuclei must contain neutrons."

The metallic bond is a force that is responsible for holding the atoms together in a metallic substance. In other words, the metallic bond occurs between two metal atoms. Metal atoms need to give up electrons to achieve the configuration of a noble gas. In this way, this type of bonding all the enveloped atoms lose electrons from their outermost layers, which move more or less freely between them, forming an electronic cloud (also known as the sea of electrons).

In other words, a metal is a set of metal cations immersed in a sea of delocalized electrons where the electrostatic attraction between positive (of the cation) and negative (of the electron) charges holds together all the atoms of the metal that forms the bond .

The metallic bond is the only bond where the electrons are not located exclusively between a pair of atoms, but are relocated among millions of them in a kind of glue or "sea of electrons" that keep them tightly bound or cohesive.

The answer is: The electrons must be attracted to each other.

correct it is c.) b b

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
