Answer:
When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. The resulting compound is called an ionic compound. In all of these reactions, the metal atoms give electrons to the non-metal atoms.
Answer:
The mass will be 90.91 kilograms, we can’t figure out the weight without knowing how much gravity is on the other planet.
Explanation:
Mass is the amount of substance a matter contains. The more the substance a matter contains, the more massive it becomes. The mass of an object is the same everywhere in the universe. Therefore, the cube will have the same mass of 90.91Kg in another planet.
Weight is a function of mass and the force of gravity on such a body. The weight of a body relies on the prevailing acceleration due to gravity in a particular place. Some places have gravity higher than that on earth and so they will have more weight. This is why we can't figure out weight without knowing the gravity in the other planet.
You need to list the elements but remember that fluorine has the highest electronegativity out of the entire periodic table
Answer:
Yes
Explanation:
A gene pool is the sum total of all the genes(sum of alleles)of a species and population at any given time is known as gene pool.
The new species are created in nature by four mechanisms such as geographic isolation (allopatric speciation), reproductive isolation (sympatric speciation), mating behaviour (parapatric speciation).
Due to any of these factors when population acquire unique changes in their genes and enough changes have been introduced in the gene pool of the population with time, two population become distinct from each other and not able to interbreed leads to the formation of new species.
