<span>The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. In this case, the atomic number of the atom is 3 and the atomic mass is 7. Hence the element is Lithium, a metal </span>

Answer and Explanation;

Structure; the nucleus has 3 protons and 4 neutrons, while the energy levels or the orbitals have 3 electrons. The identity atom is lithium atom (3 protons and three electrons) with an electron configuration of 1s^2 2s.

Charge; the atom has zero charge; it is neutral because the number of protons is equal to the number of electrons.

Its atomic number is 3; since atomic number is the number of protons in the nucleus of an atom (3 protons).

It has a mass number of 7; mass number is the sum of neutrons and protons in the nucleus of an atom ( 3 protons + 4 neutrons).

Atoms contain three sub-atomic particles called protons, neutrons and electrons. The protons and neutrons are found in the nucleus at the center of the atom. The nucleus is very much smaller than the atom as a whole. The electrons are arranged in shells around the nucleus.

In a neutral atom the number of electrons in an atom is always the same as the number of protons (protons = electrons).

seropon [69]

Answer:

Velocity = 0.5 m/s South (A)

Explanation:

You need to determine the average rate of velocity.  

The equation you will use is velocity = displacement/time

The displacement is 30m South.

The time is 60 seconds.

Plug into the equation  Velocity = 30m South/60 s

Velocity = 0.5 m/s South

Calculate the gravitational potential energy is a bicycle of mass 20kg and its rider of mass 50kg cycle to the top of a hill 120
Travka [436]

Explanation:

Gravitational Potential Energy can be calculated with the following formula:

mgh

Where m is mass, g is Gravitational Field Strength, and h is height. GFS on Earth is always 9.81, the combined mass of the cyclist and the bicycle is 70, and the height is 120. Multiplying these values together, we get:

82,404J.
