Nitrogen is a chemical element with an atomic number of 7. Also the symbol for Nitrogen is N. Nitrogen is a colorless, odorless, tasteless substance. Also nitrogen is a nonmetal.

What is Br atomic name?

bromine (Br), chemical element, a deep red noxious liquid, and a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.

Which is the element of Br?

Bromine
Bromine – Element information, properties and uses | Periodic Table.

What is the mass number of nitrogen?

14.0067 uNitrogen / Atomic mass

How many neutrons does BR have?

Bromine has an atomic number of 35, and so has 35 protons. You are told that the mass number is 79, and so there are a total of 79 protons plus neutrons. Therefore there must be (79 – 35) neutrons = 44 neutrons….Protons, neutrons and electrons.

Who discovered nitrogen 14?

Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth’s atmosphere, which contains an estimated 4,000 trillion tons of the gas.

What is Nitrogens atomic structure?

The nucleus consists of 7 protons (red) and 7 neutrons (blue). Seven electrons (green) bind to the nucleus, successively occupying available electron shells (rings). The stability of an element’s outer electrons determines its chemical and physical properties.

How many neutrons does Br have?

What is the atomic number of barium?

56Barium / Atomic number

Is Br an atom or molecule?

Because of its high reactivity, bromine naturally occurs as a bromine molecule rather than a single atom. This molecule comprises two bromine atoms that each share one valence electron with the other, forming a covalent bond. Bromine exists in a pure form as a diatomic molecule.

Why nitrogen has 7 atomic number?

The number of electrons in an atom is always equal to the number of protons. So, in nitrogen-15, the number of protons in the nucleus are seven and thus, the number of electrons revolving around the nucleus is also seven. Here, Z is the atomic number .

What is the atomic number of nitrogen-15?

Nitrogen-15 has an atomic number of 7, so an atom of nitrogen-15 contains 7 protons, 7 electrons (recall that the number of protons equals the number of neutrons), and 8 neutrons (15 – 7 = 8).

How many protons are in Br -?

How many protons and electrons are in Br?

Bromine-81 is composed of 35 protons, 46 neutrons, and 35 electrons.

What color is nitrogen?

In its gas form, nitrogen is colorless, odorless and generally considered as inert. In its liquid form, nitrogen is also colorless and odorless, and looks similar to water, according to Los Alamos.

How is N2 formed?

Nitrogen is a non-metal and it has 5 electrons in its outer shell. Nitrogen is in a group 5 of the periodic table. Complete answer: Both the nitrogen atoms will each share three electrons and thus, form three covalent bonds and make a nitrogen molecule (N2).

What is Nitrogens number of neutrons?

eight
So, the number of neutrons in the nitrogen atom is eight. Hence, seven protons, eight neutrons and seven electrons make up an atom of nitrogen-15.

Who discovered nitrogen 15?

physician Daniel Rutherford
Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth’s atmosphere, which contains an estimated 4,000 trillion tons of the gas.

Is BR a metal?

Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure.

What is the element name of BA?

barium
barium (Ba), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table. The element is used in metallurgy, and its compounds are used in pyrotechnics, petroleum production, and radiology.

How many electrons does BR have?

35 electrons
The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons.

What is the atomic number of nitrogen 7 or 31?

Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens.

What is the atomic number of nitrogen 17?

Nitrogen has an atomic number of 7 and mass number of 14, an isotope of nitrogen has a mass number of 17.

How many electrons are there in Br?

So, the no. of electrons in Br− = 36. Was this answer helpful?

What is the atomic number of nitrogen?

Atomic Number of Nitrogen. Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. The chemical symbol for Nitrogen is N.

How many protons and electrons in nitrogen?

Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. The chemical symbol for Nitrogen is N. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.

What is elemental nitrogen?

Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78% by volume of Earth’s atmosphere.

What are the mass numbers of Typical isotopes of nitrogen?

Mass numbers of typical isotopes of Nitrogen are 14; 15. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
