What element has a 2+ charge when it has 54 electrons please give the atomic symbol?

Thus, the element is Cesium. The symbol for Cesium is Cs.

What has a mass of 1 amu?

An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass.

What element has an atomic mass of 52?

The Elements, sorted by Atomic Number

Atomic Number	Symbol	Atomic Mass (amu, g/mol)
49	In	114.82
50	Sn	118.69
51	Sb	121.75
52	Te	127.60

How do you find the mass number of an element?

The atomic mass equals the number of protons plus the number of neutrons, so you find the number of neutrons by subtracting the number of protons (i.e. the atomic number) from the atomic mass (in atomic mass units).

How do you figure out the atomic number?

To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number:

number of protons = atomic number.
number of electrons = atomic number.
number of neutrons = mass number - atomic number.

What element has a 27 Atomic Mass?

Cobalt

What is atomic mass number?

The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.

What is the charge of a proton?

Proton Charge While a proton has a charge of +1, or 1e, an electron has a charge of -1, or -e, and a neutron has no charge, or 0e. 1 elementary charge is equal to: 1.602 x 10^-19 coulombs.

Where is cesium found?

Source: Cesium is found in the minerals pollucite and lepidolite. Commercially, most cesium is produced as a byproduct of the production of lithium metal. More than two-thirds of the world's reserves of Cesium – 110,000 tonnes – are found at Bernic Lake, Manitoba, Canada.

Can you tell from the periodic table exactly how many neutrons are in an atom?

Because we can find the number of protons and the atomic mass of an atom by looking at its element information in the periodic table, we can calculate the number of neutrons in that atom by subtracting the number of protons from the atomic mass.

What is Bariums atomic mass?

137.327 u

What element has an atomic number of 56?

Barium

Who discovered cesium?

Robert Bunsen Gustav Kirchhoff

How do you find the electrons?

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

What does cesium look like?

What does it look, feel, taste, or smell like?[edit] Cesium is a silvery-gold color. It is a soft alkali metal, with a very low melting point — 28C, which is below human body temperature (37C).

Why is cesium The largest atom?

Caesium with an atomic number of 55 has the largest 'atomic radius'. Because of this, it is highly electropositive( it is very easy to remove the valence electron from Caesium) and hence very reactive. Nuclear charge increases as you go from left to right in the periodic table.
