Answer:

Atoms are composed of a central nucleus which is surrounded by orbiting <u>Electrons</u>.

Explanation:

The word Atom is derived from atomos meaning indivisible particle. An atom is a very small sized particle and its size is approximately 100 picometers.

Atoms are composed of a Nucleus which contains protons and neutrons and the nucleus is surrounded by orbiting electrons. Also, the nucleus is positively charged due to +ve protons and the electrons revolving around nucleus are -vely charged making overall atom neutral in nature.

Atoms react with another atoms due to the presence of valence electrons present in the valence shell of an atom. The valence electrons would make a covalent bond by mutually sharing the electrons or it may form an ionic bond by gaining and loosing valence electron.

Which part of chromosomes passes in trait from parent to offspring

AfilCa [17]

Answer:

Genes

Explanation:

The genes are the basic unit of hereditary which are a part of chromosomes that are passed from parents to their offspring.

Genes are responsible for the propagation of hereditary features. They are usually located on the chromosome.

Genes are made up of protein molecules.

Each parent passes down a copy of their gene which are inherited by the offspring and they determine a character state.

They generally make up the genotype.

The nuclear fission of U-235 can occur by different pathways. If 1 neutron is absorbed by U-235 to produce 36 neutrons and Kr-94

motikmotik

Answer:

See explanation

Explanation:

What I have written in the image attached is called a nuclear equation. It differs from a chemical reaction equation in the sense that it involves transformations that occur in the nucleus of atoms.

The nuclear equation must be balanced. This means that the mass and charge on both sides of the reaction equation must be the same.

On the left hand side the U-235 interacts with a neutron. The total mass on the left hand side is 236 while the total charge is 92. If we sum up the masses and charges of Ba and Kr, we also get a total of 236 mass units and a charge of 92.

Hence the other nucleus is barium-141
