## What is an atom with 3 protons and 4 neutrons?

A lithium atom contains 3 protons in its nucleus irrespective of the number of neutrons or electrons. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons.

## What has 3 protons and 3 electrons and 4 neutrons?

Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7.

## What element has 4 protons 4 neutrons and 3 electrons?

The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.

## How many protons neutrons and electrons are in platinum?

It is classified as a transition metal. Platinum atoms have 78 electrons and 78 protons with 117 neutrons in the most abundant isotope.

## How many protons and neutrons are present in a platinum atom?

The nucleus consists of 78 protons (red) and 117 neutrons (orange). 78 electrons (white) successively occupy available electron shells (rings). Platinum is a transition metal in group 10, period 6, and the d-block of the periodic table. It has a melting point of 1768 degrees Celsius.

## How many protons are in an ion of platinum?

An ion of platinum has a mass number of 195 and has 74 electrons. How many protons neutrons does it have? What is its charge? Pt has atomic number 78, so it has 78 protons

## Does platinum have 78 protons?

Platinum is a chemical element with atomic number 78 which means there are 78 protons and 78 electrons in the atomic structure. The chemical symbol for Platinum is Pt. Since the number of electrons is responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements.

78 electrons

## What is electron of platinum?

Platinum atoms have 78 electrons and the shell structure is 2.8. 18.32. 17.1.

## How much atoms are in platinum?

platinum

 atomic number 78 atomic weight 195.09 melting point 1,769 °C (3,216 °F) boiling point 3,827 °C (6,920 °F) specific gravity 21.45 (20 °C)

## How many electrons are in an atom?

By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons.

Lithium

## What is the number of electrons in an atom that has 3 protons and 4 neutrons?

Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7. Knowing the mass number and the atomic number of an atom allows you to determine the number of neutrons present in that atom by subtraction.

Mass Number.

 Name Lithium Symbol Li Protons 3 Neutrons 4 Electrons 3

## What will be the valency of 3 protons and 4 neutrons?

Mass number = Number of protons + number of neutrons =3 + 4 = 7. Hence, its valency is 1.

## What element has 4 protons 3 electrons and 4 neutrons?

The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.
