Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of vanadium is 23. The electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³. The noble gas electronic configuration of vanadium is [Ar]3d³4s². 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals.

How do lions obtain the carbon they need?

by eating animals that have carbon-based molecules stored in their bodies
by breathing it in from the atmosphere in the form of carbon dioxide
by absorbing carbon-based molecules through their skin from the soil
by drinking water that contains carbon dioxide

Answers

Answer:

Explanation:

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.

What are Consumers?

Heterotrophs are known as consumers because they consume producers or other consumers. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.

Heterotrophic living organisms include all animals and fungi, some protists and bacteria, many types of parasitic plants.

Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.

Therefore, Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.

Explanation:

A neutral atom of beryllium (Be) has an average mass of 9 amu and 4 electrons. How many neutrons does it have?

13
5
9
4

Answers

Answer:

It has 5 neutrons

Explanation:

The fact that it is a neutral atom tells us that the number of electrons and protons is the same:

The problem tells us there are 4 electrons, thus there are 4 protons.

The average mass of an atom is the sum of the number of protons and the number of neutrons:

Mass = # Protons + # Neutrons

With the above information in mind we can calculate the number of neutrons:

9 amu = 4 Protons + # Neutrons# Neurons = 5 Neutrons
