Match each vocabulary term to its definition. 1. electrons neutral subatomic particles found in the nucleus of the atom 2. neutron lowest energy position of an electron in an atom 3. photon the path of an electron around the nucleus of an atom 4. ground state negatively charged, subatomic particles 5. protons packet of energy of specific size 6. element substance with only one type of atom 7. orbital positively charged, subatomic particles found in the nucleus of the atom

B

Explanation:

a substance with only one type of atom.

1. Elements

Substances with only one type of atom.

2. Metal

An element that is malleable, polishes to a luster, conducts heat and electricity well, and tends to lose electrons in a chemical reaction.

3. Metalloid

An element with properties of both metals and nonmetals.

4. Nonmetal

An element that is brittle, insulates heat and electricity well, and tends to gain electrons in a chemical reaction.

1. ground state: lowest energy position of an electron in an atom

2. photon: packet of energy of specific size

3. neutron: neutral subatomic particles found in the nucleus of the atom

4. protons: positively charged, subatomic particles found in the nucleus of the atom

5. electrons: negatively charged, subatomic particles

6. orbital: the path of an electron around the nucleus of an atom

7. element: substance with only one type of atom

Explanation:

An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.

Protons, the positively charged particles and neutrons, the neutral particles are located in the center of an atom where mass of an atom is concentrated.

Electrons , the negatively charged particles are located outside the nucleus where they orbit in different energy levels around the nucleus called as orbitals.

The electrons absorb energy in the form of photons which are packets of fixed energy and thus the electrons move from lowest or ground state orbitals to move to higher energy or excited state orbitals.

a substance with only one type of atom

Explanation:

A chemical element is a substance that contains only one type of atom. If a substance contains more than one type of atom, it is a compound. An element can be a solid, liquid or gas. The smallest particle of such an element is an atom.

An element is C. A substance with only one type of Atom

Answer : All the statements are correct.

Explanation :

For example : The molecule of hydrogen element is made from atoms of similar element (hydrogen).

For example : The carbon tetrachloride is made from atoms of different elements (carbon and chlorine) combined together in a fixed ratio by mass.

Hence, all the statements are correct.

Answer

Correct Answer are

Electron 1, neutron -6, photon-7, ground state-5, protons-3, element-2,orbital-4

Explanation:

Defination of terms is given in front of terms

Electron      1. negatively charged

Neutron       6.neutral subatomic particles found in the nucleus of the atom

photon         7.packet of energy of specific size

ground state  5.lowest energy position of an electron in an atom

protons         3.positively charged, subatomic particles found in the nucleus of the atom

orbital          2.the path of an electron around the nucleus of an atom  

element       4.substance with only one type of atom

C. A substance with only one type of atom

Explanation:

An element is a type of substance which is made up of only one type of an atom. Taking the example the hydrogen is made up of 1 proton and 1 electron. If any one look at the atom of hydrogen then he notice that the most of the atoms of hydrogen do not contain any neutrons but few of them contain 1 or 2 neutrons.

These different type of hydrogen is known as isotopes which contains same no. of protons but different no. of neutrons.

If you change the proton which means you change the element but if you change the neutron no. means you change its isotope.
